Trap: It happens when 2 or 3 creatures are about to fuse, but at least one of them gets corrupted while they do. This causes the non-corrupted to be unable to unfuse unless the fusion gets defeated (once a fusion has been weakened enough, it will seperate automatically).
Hivemind: When 4 (or more) creatures get forcefully fused by ReaMi (all of them get corrupted in the process)
