Nuclear bomb rock

The Nuclear Bomb-Rock was originally created for Pikmin: Sinister Incinerator, but it has been seen in other non-canon games as well since then. It's a special type of bomb-rock which has a slightly green interior, which can be seen through very small cracks on the outside of the rock. If it takes damage, its energy gauge will deplete at a very slow rate, taking approximately 128 seconds to reach the end. At that point, it will instantly explode, completely destroying the entire sublevel and everything in it- so you should take care to not set these off. Sometimes, it's unavoidable, though... so if it happens to get hit, finish up whatever you're doing fast and move on to the next floor. If you're at the end of your wits end with no way out, just give up and escape. Plan better for next time!
