If you could take some special skill from any animal, which animal and which skill would you choose?

Bats. Echolocation.

Chameleon- disappearing into the background when you don't want to be somewhere sounds great.

Sasquatch...they are good at hiding. lol

A viper's ability to be effortlessly venomous, but only when they actually want to fuck something up, would be pretty nice, but I'd probably go with the ant's ability to "be" 100,000+ different bodies at once.
