Tim and Mark are two birds that turn into other creatures. Tim is a normal bird who doesn't care about anyone or anything and has had 3 wifes in the previous week. Mark is affectionate and has feelings. He pleads for help when he is trapped in a box, but Tim doesn't care and says to do it himself. Tim and Mark then turn into other creatures. They were first featured in PARAKEET'S PILL PACK Shapeshifter Mod Update (Garry's Mod) video and have never been seen since.
