Nettle

Your best friends if you need to grasp the nettle and be stung into action! Rayman 3 (official description)

Nettles are invincible enemy plants found in Rayman 2 and Rayman 3.

In Rayman 2

Nettles are more common in Rayman 2 and are often found in sanctuaries. Once they take a hit, they retreat back into their holes for a few seconds. After said time has elapsed, they pop back up out of their holes. They are very strong as they are shown to break through solid rock.

In Rayman 3

The nettles have a small cameo in the Bog of Murk. There are only two here and behave in the same way as the ones from Rayman 2. They come out of the side walls and simply block Rayman's progress; as before, one hit is all it takes to do away with them for a few seconds. They are not seen again in the game.
