P.A.R.T.Y.

The P.A.R.T.Y., or Partly Annoying Random Terror of Yards, is a blimp with 365 health and 365x the speed of a B.C.F.M.B. It looks like a white M.O.A.B. with random multicolored spots on it and a rainbow-colored party hat on it and first appears on round 365. It has no abilities, as it would escape before using them. Oh, also, Healthy Bananas is useless against this guy, as he takes infinite lives!
