Backrubbers

Congress
Congress is a group that appears in The Other

Tarts for the annual Back-Rubbing Ceremony. They presumably have some influence over Candy Kingdom, since Princess Bubblegum regards the ceremony to be so important.

Appearance
Congress members are blue or green jelly bean-like creatures. They all have varrying symbols sticking out of their heads. One of them is notable for being the only purple member of congress, possibly denoting him as the leader.
