RocknRoller MR4

A heavy-set breed of Psiroller with a rockin' hairdo, this monster loves to not only race but also to sing and play loud music. Its name was shortened to just RockRoller for Monster Rancher Advance because of the character limit on names.


Its name is a play on the words Rock and Roll, a music genre helped made popular by Elvis Prestley, the man whose hairdo this monster is fashioned after.
