Welcome back to the comic! I ran out of doorway puzzle ideas for Grizzly, so I diced to set up a different kind of puzzle. I wedge the chew wall out of his reach and left just the rope hanging down. The idea was, if he could grab and pull the rope hard enough, he could get it down on his own. I saw him looking at it and contemplating it.
A week later it was still up there, so I pulled it down for him...
