Oh God, this episode made zero sense whatsoever. I liked it for the most part, mostly at the beginning and the end - but I didn't really like the middle scenes for some reason. I liked the comedy though, but I shall get into that further in my good points and bad points.
Good points
+ Comedy + trio/Meowth interactions. So many amusing faces and funny situations, Iris spitting fire and going crazy, Dento being extravagant (lol) and the gang's reaction to him. Ash amusingly thinking that Leon was actually an alien, the gang falling asleep at the bed, the twerps harassing Meowth and lastly, the twerps realizing they could have taken the car to get to Nimbassa. XD I gotta admit that this episode was great in terms of comedy. The animation wasn't that great, but I liked those bits.
Bad points
- Everything else, really. The animation wasn't all that great, the mascots were the only ones featured as always and I found the repetitiveness of the 'Jenny orders Psybeam' footage really annoying. The battles weren't anything great, this was just a classic example of a filler.
Overall, a somewhat fun episode. Like I said, I only enjoyed the comedic moments since everything else was just crap. Meh, I guess that was good enough. ^^
