Blue Mudbeast is a boss in Chrono Trigger that appears in the Mudbeast Den in 12000 BC. It is teamed up with the Red Mudbeast, and Mud Imp. A very effective strategy for this battle is to use Lucca's Hypnowave. It can disable both Mudbeasts, while the Imp attempts to wake up his Mudbeasts. The Imp himself has high defenses, but will fall soon enough to magical attacks.
