Idea: Poisonus spider - Alive; Very small and has very low health; Can crawl ragdolls and bite randomly; After bite ragdoll gets poisoned; Ragdoll will die if biten too much.
Idea: what about weld and freezing? Weld: allows to weld objects and ragdolls, example: ragdoll that holds gun, tower made of squares. Freeze: allows to freeze ragdoll or object and then use weld without risk, example: ragdoll that holds gun (again), freezed ragdoll-fighters, freezed axe that acts like 'draw WALL'.
