Tip and Dash
Tip and Dash are major supporting characters in the Kingdom Hearts Unlimited Saga, first appearing in The Second Trilogy as Melody's partners for the events of the Atlantica campaign.
Tip, a penguin, and Dash, a walrus, are two best friends who dream of becoming heroes. The problem? They're both cowards in the face of real danger, and they tend to cause more harm than good. Still, when push comes to shove and their friends are in dire peril, the two will eventually overcome their fear to show the baddies who's boss around here. Tip and Dash eventually become Melody's familiars when the young princess gains control over the Mini-Moon Crystal.
(Think of them as the counterparts to Timon & Pumbaa and Diana the Moon Kitten)
