Hint: Defeating Bebop:
When he swings his mace at you, quickly jump kick over him and attack him back on.

Hint: Defeating Groundchuck:
Contiguously attack him, but jump and do not waste time trying to attack him while he charges. When he uses a pipe on you, get close to him so that he cannot hurt you, but you can still hurt him. Be alert when he charges you again, and continue this cycle until he is defeated.

Hint: Tubular Turbo Attack moves:
Perform the following moves by pressing A + B. Note: These moves will take a bit out of your enemies, but also do damage on yourself. They require one unit of energy per use. If you have one unit of energy remaining, you can still use the Tubular Turbo Attack move as long as desired, but watch out for enemies.
