Yeah Pete, I think some research could help us understand Jr, both as a Pokemon himself and with human's influences on him!

[Ray means that he's going to try training the Grimer like a dog.

He then awkwardly rubs the back of his neck with his free hand.]

I can at least see if I can make you a suit that resists the toxic ooze given off by Jr.

[He does feel a tad guilty for giving Peter a pokemon that could kill him with toxic ooze.

Just a tad.]
