Rainbow Pupsters are Dog-Rainicorn hybrids. They are offsprings of Jake and Lady Rainicorn. Jake was surprised when he found out that he was going to have puppies. They were first shown on Princess Bubblegum's Heart Monitor, in the episode "Lady & Peebles." The 5 children are born in the episode "Jake The Dad."
