7x20 - Dragon Ball Z: Dragon Box

Boo is blown to pieces by the Big Bang Attack that Super Vegetto unleashes on him. Boo tries to regenerate himself again, but unlike all the previous times, he has taken a considerable amount of damage. Boo begins to feel pressured by Vegetto's devastating strength, and when an opening presents itself, he slips inside Vegetto's body! He attempts to destroy Veggeto from the inside, but his atacks end up having no effect.
