Prickly ball
Spiky balls (also known as prickly balls) are dangerous blue objects from Rayman. They exist in various sizes. The most common kind, of small size, possesses eyes and randomly looks around itself: they are found in all words but Dream Forest. The other kind, of much larger size, has no eyes and is sometimes attached to a rocker. If it's not already spinning, Rayman can knock it but he must be careful not to get hurt. They are only found in Blue Mountains and the Caves of Skops.
In the Rayman Junior games, there are red spiky balls of both sizes, and if Rayman touches them, he will instantly lose a life.
In Rayman Designer, a green version of the small spiky balls was introduced in Dream Forest. Except for the colour, there are no differences with the blue ones.
