“Maybe I’m glossing over the story and I’ve missed something, but I’ve just freed Bruno and Trixie and it feels weird that there’s more game. Wasn’t that the goal from the beginning? And now Sam and Max are just… doing more stuff… because reasons?”
Why Sam & Max are set to get into the Yeti convention isn’t entirely clear to me, but once inside the elder Yeti explains they’re a dying species and Sam (Max less so :P) decides to help them out, rather than returning Bruno to the circus.
