Starbomb

The starbomb (not star bomb or star-bomb, ala spacetime) is the holiest of attacks. It can occur when one has both a star and a bomb in inventory. It is performed by first using the star, rendering yourself invincible. Then a forward banana-peel-like attack is performed so that your opponent is hit by the bomb, the blast radius of which you are in (due to the forward attack). The invincibility, however, allows you to emerge unscathed. This can similarly be performed with a non-forward attack, but must then end with you running into the bomb, exploding it, hitting your enemy, and you escaping. To recap, four requirements must be met to have executed a starbomb:

1. Your enemy is hit with your bomb.
2. You purposefully trigger the bomb either by a successful forward attack or running into it yourself.
3. You are within the blast radius.
4. Your enemy is the only one to lose a balloon due to your star-powered invincibility.

We have only achieved this once, due to accident. It was so awesome, however, that we named the occurrence and have striven to repeat it.
