Oogaroo is Blue Blumaroo who is one of the players of the game Tyranu Evavu in Tyrannia. He is not to be confused with the very similar Uggaroo from Go! Go! Go!
He says two things;
- "Graguda Tyranu Evavu! Gedd lacka."
- "Uhhg Uuuuuuhhhhgggg!"
Uggsul, JarbJarb, and Oogaroo are the three Tyranu Evavu players (Daily Puzzle from the 12th day of Gathering, Y9).
