Lure Location One
This Lure Level Up Item is located in Station Square, near the same location as Tails' Jet Anklet. To obtain it, the player must go to the area behind Twinkle Park, where there will be a small canal that leads into the sewers. The Lure Level Up Item can then be found at the end of the canal, which is blocked by bars.
Lure Location Two
This Lure Level Up Item is located in jungle area of Mystic Ruins. When standing at Big's hut, the player must go down the second path from the left in front of Big's hut. The player should proceed down the path and then take the second path on the left, where they will find themselves in a small clearing where the Lure Level Up Item is found.
Lure Location Three
This Lure Level Up Item is found in the Icecap and is the only Lure found in a Action Stage. To reach the area where the Lure is located, there are two paths Big can take; when beginning the stage, the player can do one of two things; either go up the stairs on the left until Big reaches a small pool that leads to another area, and follow the path until Big reaches a area with dinosaur bones on ice and a pool covered in ice. Or alternatively, they can jump into the pool near the beginning and follow the path on the bottom until they enter a new area, where they must surface and take the Springs in front of Big which will take him to the same ice covered pool. The player must go into this pool by breaking through the area with thin ice and dive to the bottom. The Lure Level Up Item can then be found there.

The player must go to the holding cell area where Amy Rose was held upon her capture by ZERO, and the Lure Level Up Item can be found in the cell closest to the door.
