Jolly and Olly are the stars of the game Jolly Jugglers. The two of them are best known for their expertise with their weapons, going up to save their sister from the evil Mutant Chia who kidnapped her, being feverishly envious of the Jolly Jugglers for an unknown reason. They are probably twins.
Do you know we're the best jugglers in Neopia? Also the only known jugglers in Neopia, but that's totally irrelevant. Stand back and be amazed by our skills!
Jolly is the Green Chia; Olly is Purple. They are both mentioned in the King Roo Neopedia article.
