Jumping eyes are some kind of static enemy, which do not move or attack and just stay in one place, jumping endlessly, sounding like a bounding ball. They can hurt Rayman if he gets too close to them. They can be destroyed in one hit. They seem to have some connection with Jano and the mini Janos; they resemble their cycloptic eyes, are usually found in their territory.
They appear in Rayman 2, but not Rayman Revolution, or the PlayStation version of Rayman 2. They are met only three times: in front of the entrance to the Cave of Bad Dreams; the area inside the Cave of Bad Dreams where Rayman finds a blue Magic Sphere; and in the first part of the Sanctuary of Rock and Lava. They also appear on the big root before reaching entrance to the Sanctuary of Rock and Lava.
