This is Hase's story as written on his tag:
" He was a member of the Hot Black Rabbits – a legendary band in BeastsTown in the 60s who made a name with their hare-raising concerts. They destroyed plenty of Easter eggs, not to mention entire hotel rooms, along the way. Rumpelfilz has grown older, of course, but he hasn’t lost any of his star appeal. Today he still lives off of the royalties earned from his BeastsTown world hit “BeastsTown, BeastsTown” (later adapted by Frank Sinatra into “New York, New York”)."
