If you have any combos with any mutations you can put them here instead of making a discussion. I got 3.

1: Centipede Mute requires the serpent syringe and arm>leg syringe. Bit laggy

2: Jellyfish+ Mute requires the jellyfish syringe and limb syringe.

3: SporeNow requires the serpent syringe and spore syringe. Combining these two will cause
alot of spores to be spawned in. Make sure the serpent has took it's full effect.
