Jerkweed

Jerkweeds are common sights in Kirby Mass Attack.

In Kirby Mass Attack
Jerkweeds are green (brown in Sandy Canyon) vines that hang from ceilings, and can be pulled by the Kirbys. Once oulled, the jerkweeds will reveal either a key, fruit, a medal, or an enemy/enemies. There are also some jerkweeds covered in thorns, and they cause the Kirbys to take damage if they touch it. However, the jerkweeds with thorns will turn into regular jerkweeds continuosly, so good timing is needed to grab these jerkweeds without taking damage.
