If you have a hard time getting going on a cold morning, ...consider the fence lizard.
On any normal warm Florida day, these guys combine excellent camo with ninja-like speed to avoid capture. On an oak tree, they practically vanish due to their superbly adapted coloration.
If that doesn't work, they are experts at squirrelian scrimmaging to whatever side of the tree you are not on.
...BUT, catch them on a cold morning and their supereptilian powers are nullified.
