Candy barbarian

The candy barbarian is one of the most OP characters in the game So if you see one in battle area take it seriously cause it can kill you with ease and it will

It uses PHYSICAL attack. Magic attack does nothin. (Wiki)

Finish the job
one of the attack combos that can come in handy is RB+RT+RT+LT and if he isn't dead LB. the translation is dash attack, to standard sword attacks, spin attack and if he isn't dead ice cream. It can do major damage over time and weaker enemies won't stand a chance, it even works (sometime) on battle!

Suprise attack
simple and deadly press LB and press RB whenever possible to activate gumdrop passive use LT 2 times and keep pressing RT with RB when possable. And once more another good battle strategy

Death to all
press LB+RB+RB+LT and repeat with RT if you run out of stamina ( all strategies to battle )

bonus and attack
pressing LB+a lot of RT and LT whenever possible you can bring and win a fight

bonus:pressing RB in water triggers super jump and it is possible to get out the water just by using that RB button
