Turns out the former Chipmunk who's now working for Tony and revealed their stash to him later sneaks snacks to the kids, and Pat.
Of course, it's mitigated a bit, since he's getting paid for it.
Pat helps Gerry by giving one of the recently-dismantled go-karts a push so Gerry can feel what it's like to drive one.
At the first weigh-in, Tony calls one of the kids "the fattest kid in the camp", obviously in an attempt to humiliate him. The other Chipmunks clearly look uncomfortable by the bullying and then start cheering for him as though being the fattest kid is an accomplishment seemingly to undercut the bullying.
When Gerry gets beaned during the baseball game, Roy goes to check on him, offers encouragement, and hits a camper from Camp MVP with a bat when he starts teasing Gerry.
When some of the Chipmunks are painting a mural to commemorate the Bushkins, Sim helps Nicholas paint his portion of the mural after he finishes his own.
