Deepwood Weald What is this, a crossover episode?

Mr. Peanut Butter whines when she admits to not having any food. She doesn’t offer to help him, either, like Blackbear did, and so he sighs dramatically to make it more obvious. “I’m Mr. Peanut Butter. That’s my name,” he tells her after a moment and shrugs his good shoulder, which elicits a strangled sound from his throat by pulling on the bad. “But peanut butter is like this sweet brown stuff that kinda sticks to your teeth for a while. It’s good. I wish I had some right now.”
