Kif sure has some weird abilities... in 3ACV01 we "discovered" his ability to walk in the ceilings; in this episode, we get to see his camouflage reflex (hmm, wonder why didn't he use THAT to escape the amazonians) and explains he has no bones (he's maintained by a system of fluid-filled bladders... ewww), and then in 4ACV01 we'll get to see how pregnancy works for them...
As Mr. Spock would say... "fascinating".
