Lucas isn't finished gorging himself - he soon goes after roco the Vaporeon, and uses his psychic powers to grab the tasty little morsel and scarf him down (and also getting a nice hat!)

...just one problem. Lucas has scarfed down a Pikachu, a Lucario, and a Vaporeon...he's gonna need time to rest to burn all that off...and a stuffed, immobile Mewtwo is a vulnerable Mewtwo...
