In The Snowball Effect, he and the other Rhinos use their Legend Beast's fire roar to convert rocks into bars of gold, silver and steel. When the mammoths attack, he, Runk and Rogon snowboard and play hockey and the mammoths join in. When the mammoths decide to attack under Maula's orders, Rinona comes to the rescue with the Rhinoceros Legend.
His name is a pun on ruckus.
He and Runk are constantly confused with each other.
