Shabom

First appearing in and found Inside Jabu-Jabu's Belly, the Shabom is a bubble that will bounce off walls and floors in random directions. It will pop upon death, or upon contact with Link, killing itself but also dishing out light damage to anyone nearby.

Deku Nuts are the most effective way of killing Shaboms, as the resulting flash can kill several at once without the need to aim. The Boomerang found partway through Jabu Jabu's Belly is also very effective. While a sword slash is perhaps the most obvious way of slaying them, the resulting pop will damage Link if he's too close. Throwing Princess Ruto through them can also defeat Shaboms, but this is clearly the least effective means of attack. Since these bubbles move slowly, and never show signs of targeting Link specifically, it's often easy to just run past them without having to worry about engagement.

Trivia

 * In the Prima Games guide, Shabom is misspelled as Shaboom.
 * Navi's comment about the Shabom bouncing off Link's blade is inaccurate. It never does that, but instead it explodes and damages Link if slashed at. In the release of for the GameCube, the description has been made more accurate. The hint was later completely changed in the 3DS version, which simply warns Link not to touch it.
 * Shaboms can be defeated with a roll attack.
 * Bubbles resembling Shaboms appear in, although they cannot hurt Link. Instead, they are found encasing some Stray Fairies.
