One of the cool things about aye-ayes (come to think of it, what is NOT cool about aye-ayes?) is the fact that when they get excited or agitated, their long, mostly white, guard hairs stand on end and give the poofed up lemur the appearance of an animal twice its actual size. This adaptation perhaps evolved as a strategy to make the aye-aye look more threatening to would be predators, but you can also see it at other times when they are not being threatened. For instance techs have reported seeing it during play behavior between a mom and an infant or juvenile, and it can also be observed in instances similar to those with Grendel here: he just got moved to a brand new room in the 07 core from his old room in the 019 core. The size and shape of the new room is exactly the same as the old, but the layout of branches and many of the smells are totally different, and Grendel is just not sure what to make of it!
