Buddy Gecko is a famous American vocalist known as the "King of the Lounge Circuit" and a literal lounge lizard. His name is a take-off of the real-life American singer Buddy Greco. Gecko and his music are greatly admired by Filburt who secretly hopes to emulate him. His oeuvre includes at least one album: Loungin' Around.
Obviously, don't nominate any human characters. Hybrids like Cheetah or The Lizard are okay, as are shapeshifters with one set animal form (eg Professor McGonagall.)
