The Lilytraps takes the form of green lily pads with purple flowers on them and water sprouts coming out of the flowers, both as an icon and on the tracks.
In gameplay, the Lilytrap can only be obtained at random from Item Boxes by Big. As with most other Items, Metal Sonic can also use the Lilytrap if he uses the Steal Item to steal it from the aforementioned user.
Once obtained, the player can utilize the Lilytrap by pressing its icon on the bottom of the HUD. When used, the Lilytrap will drop its lily pads some distance ahead of the user's current location on all the lanes. Shortly after being deployed, half of these lily pads will then produce water sprouts that are too tall to be jumped over; which one of these lily pads that will make a water sprout is chosen at random. If a character, including the user themselves, touches the lily pads with active water sprouts or their water sprouts themselves, they will take damage, causing them to lose Rings and slow down momentarily. To avoid the Lilytrap, the playable character must run over the lily pads that do not emit water sprouts.
The Lilytrap can also be upgraded by leveling the user up to level 4, 10 and 16 respectively. For each upgrade, the player will increase the damage dealt with the Lilytrap.
