This is the toy tags for 3 characters - Finn, Lumpy Space Princess & Jake The Dog. You can play these characters in the Lego Dimensions game. The character tags works on all console versions of the game PS3, PS4, xbox 360 and xbox one. The game is also backwards compatible on PS5 and xbox series consoles. 

The Finn character toy tag not only gives you the Finn character to play in the whole game but it also unlocks extra DLC for the game

It unlocks a special Adventure Time story/level/adventure PLUS it also unlocks the Adventure Time world which has quests, races, things to build and is a new area to explore.

Also included is a vehicle tag which is currently programmed to be the arcade cabinet. This is a special vehicle which allows you to unlock and play midway arcade games hidden in the original game. 

If you don't want the midway arcade cabinet vehicle then you can overwrite the tag with any vehicle you unlock in the game.
