The bomb is not only used to blow up the drink machine at the drive-in theater. If you're low on health and you're desperate to get some without risking your life to kill enemies, use the bomb to blow up toilets. It will leave behind food to get a little healthier. Toilets are found in these stages.

1. The Drive-in.
2. The Ice Cream Shoppe in the Turbo Mall 2000.
3. The lavatory at Highland High.
