Colin

Colin (ウコン) is one of Tibby's friends in Rhythm Heaven Megamix.

Description
Colin is a light-yellow creature similar to his friend Tibby. He has visible lips, an affinity for all things sweet, and a doorknob on his belly. He is a guardian of Heaven World. Tibby describes him as looking spacey, but really dependable, especially if he is needed as a heavy weight for something.

Story
After Tibby and the player clear the trials at The Fourth Gate, they reach Mamarin Palace, where Tibby explains how he and his people are guardians of Heaven World and are fated to grow up into palaces, just like Tibby's Mom is. Tibby talks about it with pride, as Colin shows up, having been searching for Tibby to tell him about his mother's condition. He says that after the skies went gloomy, Tibby's Mom's face turned scary, and her voice got spooky, as though she were possessed. He doesn't know what's going on, but suggests that Tibby climb up to the top of the palace and ask her face-to-face, but the entrance is locked up. He believes this is because of the bad flow coming from the two towers next to the palace, and that clearing the Rhythm Games within will open the door. Tibby briefly praises "Colin the Brain" for this plan, before Colin reveals it was Bertram who came up with it. Colin warns that the towers might contain some powerful enemies, but Tibby knows it'll just be more Rhythm Games. Apparently, while Tibby and the player were busy with restoring flow to the towers, Colin was busy eating jellybeans he found on the floor. After both towers are restored, Colin is impressed and urges Tibby to go through the palace door and talk to his mother, prepping him up for the final challenge. During the Gameplay Counts at the end of the story, Colin is seen blowing bubbles with his friends.

Colin also appears in Rhythm Tengoku The Best Plus Comic. In 19テビリとウコン (Tibby and Colin), Tibby meets with Colin, and notices how the latter's belly looks like a door. Colin claims that it is, and opens it up for Tibby to see inside. In 23テビリとバッタ (Tibby and Bertram), Tibby tells Bertram about Colin's belly being "that". Bertram, now sweating, comments that Colin's belly is "cool", which confuses Tibby. Bertram tries to correct himself and says it's "cute", which confuses Tibby again. Bertram tries to assure him that he knows what they're talking about. In 31テビリとイヨカン (Tibby and Betty), Betty comes to Tibby to complain about how her friends have mistreated her, in Colin's case being that he ate all her snacks. In 33レスラーとファン (Wrestler and Fans), Colin appears alongside his friends taking their picture with Wrestler.

Trivia

 * Tibby mentions that he will someday grow up into a palace just like his mother . As Colin is of the same species, it is implied he will also grow up into a palace himself.
 * The fact that he can open his belly like a door shows he has already started the gradual transformation, which also implies he is the oldest among his friends.
