Monkey sub pops camo with 4-0-0 (not 0-0-4) and even 2-0-0 if there is a camo seeking monkey for its rangefinder. Also a ninja 0-0-0 can pop camo. also a 2-0-4 Glue Gunner can pop camo if someone else pops a glued bloon (glue left on the track can get grabbed by camos) Shoot, copy pasted it wrong, thanks!
