Pendora is 2.5 meters in height.
Bellsprout is 0.7 meters in heght.
Anyway don't be mislead by 2.5 meters because it accounts for the body length not exactly the difference of it's head to the ground. Notice that Jalorda's height is 3.3 meters which impossibly accounts for the difference between the top of his head to the ground.
For Pendoraa to stand, more than 50% should be distributed to the lower portion parallel to the ground meaning Pendoraa could easily stand on just 1.0 meter at most.
Using the picture you shown Muk is twice as tall as Bellsprout meaning Muk should at least be 1.4 in height, somewhat comparable to Pendoraa's 1.0 to 1.2 when it stands.
I know about how the snakes in pokemon get their length measured, but the thing about Pendoraa is that its not going to be 1 to 1.2 meters tall as it stands, though I agree it's also not going to be 2.5m as well). Just look at the opening.. In the final shot, the thing is almost as tall as Zekrom (2.7).. And is taller then Ononokusu (1.8), you just have to account for the perspective, but it's definitely bigger..
Anyway it doesn't matter as Ash just simply isn't going to get his sixth pokemon by the ninth episode.. That and this is the world where I (6ft) would be taller then a Charizard or Blastoise, although they're portrayed as massively huge as well..
Screw what I said. Mamepato better be female! Good thing I never catch any starter bird in any regions cuz if I did, I would most likely get a guy with a pink mask.
And let's check the apperances:
Pikachu: 5/5
Mijumaru: 5/5
Pokabu: 2/2
Mamepato: 1/4
Let's compare Mamepato with previous starter birds that Ash has, based on the first 10 episodes after it's capture (capture episode counts)
Pidgeotto: 6/10
- Ash had 6 pokemon in the ten episodes after its capture: (Pikachu, Butterfree, Pidgeotto, Bulbasaur, Charmander, Squirtle)
- Most of the captures happened at the end of this ten episode stretch, so there was ample screentime for Pidgeotto after the capture.
Noctowl: 4/10
- Ash had 6 pokemon in the ten episodes after the capture: (Pikachu, Bulbasaur, Chikorita, Cyndaquil, Totodile, Noctowl).
- As it was the last capture, it already had to compete with five other pokemon.
Taillow: 9/10
- Ash had 3 pokemon in the ten episodes after the capture: (Pikachu, Taillow, Treecko).
- It got enough chances in the first twenty episodes, though it didn't do many memorable deeds at all.
Starly: 9/10
- Ash had 4 pokemon in the ten episodes after the capture: (Pikachu, Aipom, Starly, Turtwig).
- It had to share more time with three other pokemon, but got standard use.
Mamepato: 1/4
- Ash has 4(5) pokemon in the ten episodes after the capture: (Pikachu, Mamepato, Mijumaru, Pokabu, (Tsutaja).
- Wasn't used when it could've been used, and now it has to share the screentime with three(four) other pokemon that are starters that will get more screentime simply for being just that.
So basing on previous starter birds, Mamepato has the worst so far. But if Mamepato appears in Ep 6, Ep 7, Ep 8, Ep 9, Ep 10 and Ep 11, it will have 7 appearances in it's 10 first episodes. And it's not like all the birds did much. I can't really remember any of them doing anything note worthy, except for their debut episode and maybe Pidgeotto's battle in Brock's gym and Starly's evolution.
In Pidgeotto's defence, it had like 8 battles in those first few episodes.. Which is actually quite a lot for a regional bird at such an early stage..
I'm not sure using Muk of that old makes any sense, considering Muk is like now as big as Ash or bigger possibly, I suppose if you were using that picture because it was near the time of its capture, then fine. But still Muk isn't exactly a small Pokemon. And then what about Snorlax, even if it didn't have its Munchlax pre-evolution time, it's still pretty much Ash's biggest Pokemon and he caught it as is. So I guess if Pendra was a stand alone, Ash catching it would be more believable?
And while I do agree that Ash won't catch Pendra (honestly if the writers had to have Ash catch a sixth Pokemon at this stage, I'm pretty sure something else would've made more sense). Heck even though I don't want it, Ash catching Ishizumai would be preferable over fully evolved Pendra. Of course there's a problem though, if Ash were to hypothetically catch Pendra, why wouldn't Ash catch it if he had 6 Pokemon already. Do they really want us to believe he'll keep Pendra on his team for X amount of episodes.
Though I do agree on one thing though, Ash shouldn't catch Pendra and keep it on his team. I mean just imagine Ash sending out Pendra against possible Shooti in the next episode, Pendra does give Ash an unfair advantage over Shooti should it actually listen to him, assuming Pendra isn't weak.
And I'll say it again if anyone catches it then Iris would make more sense since her Kibago is directly involved with the episode. But some people disagreed.
And no on Mamepato evolving unless it beats Pendra as in swirly eyes (it would still be more than what Taillow or Starly ever did in the anime before evolving).
Edit: And why is the Pink Mask so horrible, have you seen what a female Kenhorou looks like (ignoring Sugimori art) that thing is the most hideous looking bird I have ever seen. Thank God that the Pink Mask will save it from being the ugliest bird Ash has ever had. I hope the writers don't screw it up.
I could pretty much agree to this.. So case closed? Especially with the whole idea of the animé taking a lot of the length issues with a grain of salt, with what I wrote above and another example: Seviper changing sizes between episodes.
Those numbers are completely useless unless you factor in the amount of pokemon in Ash's team total. By BW10 ash will have had 4 pokemon and possibly 5 pokemon.
There are more factors to appearences then just "when was the last time it appeared/how much eps in a certain amount of time".
I'll put in those standards.. With those I still make up that Mamepato had it worst, followed by Noctowl, followed by Starly, Pidgeotto and then Taillow, although it did absolutely nothing memorable with the position it was in.
Pidgeotto was part of a three man team the first six episodes after it was caught and battled a lot in those episodes. While Mamepato did absolutely nothing in the episodes after its debut and now the next time we'll see it it will have to contend with starters, which is a horrible position to be in, as they are obviously more fleshed out most of the time. Noctowl had a similar problem, but had its shinyness to compensate, it was also the new thing, and Mamepato isn't the new thing anymore, it's the forgotten bird.. Starly is the middle child.. It didn't have a horrible position, nor did it do anything to extraordinary.. Once more, from worst to best exposition in the first ten episodes (or how far we've been thus far):
Mamepato: Was new, but isn't anymore since the starters are taking all its limelight away with backstories and interesting character quirks.. It has been undershowcased as well.
Noctowl: Got into the crew as the sixth slot and thus was the new thing, though it had the starters to contend with and stole its limelight.
Starly: Is the middle child that got its spot through the flying job, but never did anything else until it evolved.
Pidgeotto: Wasn't neglected at all and fought enough battles to stand out in the first ten episodes, after which it got backseated to the starters.
Taillow: Wasn't neglected at all, and didn't have a ton of pokemon to compete with.
