Spring (Super Mario Galaxy)

Banekiti (referred to by Prima as "springs" ) are extremely rare, indestructible obstacles appearing in Super Mario Galaxy. They resemble yellowish brown ovals with two beady eyes and four sprouting springs. Banekiti move from side to side in order to bounce and delay Boo Mario, thus hindering the passage. Only four Banekiti appear in the entire game, and only in Boo's Boneyard Galaxy. The player's character cannot affect them at all.
