Mr. Terrible starts the round. He uses Weakening Blow just like his counterpart Terrible Turnip. Start by using Cleansing Rain. You can burn him down quickly with the strider using a double Pump, then Water Jet.
Sloppus is pretty straight forward. You can choose to light him up with the strider and ride the round out, or flip into the protodrake. I chose the drake to utlilze protostrike, negating the Chew damage. Just keep the rotation up and sloppus will join the carrot brothers in the primordial stew. Watch the Video Below fo rthe one shot!
