Shrapnel

Shrapnel is an enemy found at various locations throughout Treasure Trove Cove and Gruntilda's Lair. This explosive baddie will chase Banjo along the water's surface when it sees him. Since merely touching this floating aquatic mine will cause it to explode, costing Banjo two honeycombs, it is usually best merely to avoid it; however, if and when the opportunity presents itself, Shrapnel can be safely dispatched from a distance with three Blue Eggs.

In Banjo-Tooie, colorful Shrapnel can be be found deep underwater in the Mini-sub Challenge game. Shooting a red Shrapnel will get you 1 point, greens earn you 2 points, and blues 3. Touching one will still cause it to explode in your face, so try to steer clear and take them out from a distance with torpedoes.
