Yorbie: Episode One

Pipe Bombs are long-fuse explosive weapons. When I say long-fuse I really mean it, too; after throwing out a bomb it will take roughly 5 whole seconds to actually go off. The hard part to this is finding a group of enemies packed closely enough to kill 3 of them, especially considering the surprisingly low damage output of the weapon.

Any level with multiple enemies stacked together that you can see ahead of time (before pulling them) can be used, so keep an eye out for large groups and then fire a bunch of bombs into the group. Enemies won't attack you unless you come close to them or deal actual damage, so take advantage of this and toss a number of bombs their way.
