It all looks okay, so far. Are you getting any errors? If so, what are they, in detail?

Herein lies the problem. You have this (starting line 33) -- "if crab touches middle of crab, then end game." Your enemy is not involved as coded.

Remove lines 18 thru 26 in poison class. Replace lines 32 thru 34 in Crab class with:
?
1

Actor poison;
poison = getOneObjectAtOffset(0, 0, poison.class);
if (poison != null)
