Hi Kyle, I think I know all three of your choices. Big Jeffy was a member of Little Jerry and the Monotones. He was the blue AM with brown mustache and beard, wore a top hat, and a sort of caveman-like clothing. As for #2, are you refering to Maurice Monster? There are two SS characters with that name: one is the character who was part of the Monsters Field Trip shown on Season 31; the other one being a blue monster with a sort of green-yellow tearshaped nose and a nasal voice. Oh and the bunny might have been either Howie or Benny Rabbit. If this rabbit character appeared in a sketch with Cookie Monster where CM read a poem about cookies, then that was Howie. If this rabbit character appeared on the Street and looked like a bellhop, that was Benny Rabbit who worked as the bellhop at the Furry Arms Hotel where we're currently staying with all our roommates. Hope this helps and have a good night.
