What's wrong with the crabs?

[Char1016]

So, in my Emerald I put in Day-Care a Corphish and another Corphish. They made an Egg, I hatched the egg and then I evolved him at level 30 into Crawdaunt for 10 or so minutes, he was damn easy to train. I just saw that something was going so fast there. I have a Emerald ROM for experiments, I just got a level 2 Crawdaunt and a level 100 one.
So, I was just amazed, here see it:

So, what's wrong with him, once in level 2 needs 9 experience points to go up to level 3, once in level 100 has 1640000 experience points, which are more than a legendary pokemon. And, I don't know what's going on there.
Sorry for saying ROM

One, Corphish and Crawdaunt aren't crabs, they're like lobsters, but um crawfish or whatever.

Two, since you're using a ROM, and have a Lv 2 Crawdaunt, which is impossible, well, no.

Three, some Pokemon are like that and may need more EXP than some legendaries.

Four, if you flip it over, you can hit its weak spot for MASSIVE DAMAGE.

Five, thread closed on account of ROMmage.
