Crab Bomb
From Data Realms Wiki
Crab Bomb is a term generated on Data Realms' Fan Forum for crafts (generally Drop Crates) filled with crabs (which were used because they were free, limiting the cost to the craft used).
Upon landing, its mass will be high enough to gib the craft on contact, releasing all the crabs at once. If the number of crabs is enough to go past the MOID (Movable Objects with GetsHitByMOs set to 1, like guns or actors, including their attachables as separate MOIDs) limit, older MOIDs will be gibbed to keep only 256, regardless of their type, team, position, etc.
The "Look, sir, free crabs!" pricing special was ended as of Build 27, along with crabs being for sale at all. This can be changed in Wildlife.ini by setting Buyable = 1. But that's cheating.
