Thing type 312, Emerald Token, is a type of Thing that allows the player to enter a Special Stage when collected. After finishing a level, the player gets as many chances in the Special Stages as the number of Emerald Tokens they collected in that level. Most stages have more than one Emerald Token, so if several are collected, the player can go to the Special Stages several times. If the player already has all seven Chaos Emeralds, they will receive a continue upon collecting this item.
Up to 30 Emerald Tokens may be placed in a single level. Giving an Emerald Token the Ambush flag will make it float 24 fracunits above the ground. All Emerald Tokens that are not already floating above the ground due to Z offsets should have this flag because items that do not float are difficult to collect and look as if they were stuck in the floor. The flag stacks on top of the Thing's regular height, allowing Emerald Tokens to be a total of 4119 fracunits above the ground at maximum.
