The Lilytraps takes the form of green lily pads with purple flowers on them and water sprouts coming out of the flowers.
In gameplay, Lilytraps can only be obtained at random from Item Boxes by Big the Cat. As with most other Items, Metal Sonic can also use the Lilytraps if he uses the Steal Item to steal it from the aforementioned user.
When used, lily pads will be dropped some distance ahead of the user's current location on all the lanes. Half of these lily pads (which are chosen at random) will then produce water geysers that will inflict damage on anyone who touches them (including the user). Also, due to the geysers' height, the player cannot jump over them. To avoid getting hit by Lilytraps, the player must run over the inactive lily pads.
