Hello, maybe it's known bug, but I didn't see anyone yet to report it.
When you get Theodor in angry mode (when he's just walking pretty p*ssed off), then his gloves melt over his arm...
This happenes only when he's in movement (counting walking, running and chasing.
Thanks for checking 
#Neighbor has niiiice stretching gloves!

That happens with Gerda's Gloves too, when she gets painted
That's...stretchy indeed. Thank you for letting us know! 
Also, how do you get Theodore in angry mode?
You either step on noisy traps a bunch of times or you can just throw a lot of paint cans/Trash bags
