Apple juice

In BZPB, several characters own some kind of apple juice which they believe makes them more powerful. QQQ started this phenomenon, who drank apple juice during his confrontation with Yon. Whether or not it actually gave him power is unclear.

Willy Wonka accused the Hungry Hungry Hippo of stealing apple juice and contaminating the Caged Bagel with it before their confrontation with Blackout. The Hippo did this because it thought it would make the bagel more powerful. The results were unclear but the bagel ended up being bludgeoned to "death" anyway.
