Eating a muscle sprout hurts the player and slows them down, so what if there was a way to use them against bugs? Maybe an arrow that has bits of muscle sprout that hurts the bug, or maybe you can use the lure trap to trick bugs into eating the muscle sprouts? There are now Spicy, Minty, Fresh, and Salty globs, so maybe you can turn the muscle sprouts into a glob, add it to weapons, and get a new type of effect on weapons. Combining a muscle sprout with an ant egg and fungi could make a muscle sprout bomb, with the same idea. I feel the muscle sprout needs more use, as it is only used for smoothies as of now.

The sprout hurts you because it actually fights back during being eaten. Check the hams logs. If it were a weapon it probably would be a lure like trap that grabs the bug. Kinda like a bear trap.  Not saying bear traps can't be used as a weapon. It's just usually attached to a chain and tends to be a exceedingly brutal weapon
