Killdoor
Killdoors are objects in Rayman Junior and Rayman Designer which trigger the disappearance of certain events, usually ones blocking Rayman's path. There are two types of killdoors available: normal killdoors and Ting killdoors.
In Rayman Designer and its spin-offs
Normal killdoor
Normal killdoors are not visible to the player and trigger the disappearance of one or multiple events when Rayman comes within range. They are usually set to trigger the disappearance of events blocking Rayman's path.
In Rayman Designer, there are several types of normal killdoors available. These are the super killdoor, killdoor size 1, killdoor size 2, killdoor size 3 and killdoor size 4. The super killdoor maintains its effects if the player dies, while the others reset. The size determines the range of the killdoor. Size 2's range is 50% larger than size 1, size 3's range is 100% larger than size 1, and size 4 has the same range as a Ting.
Ting killdoor
Ting killdoors are activated once all Tings of a specified colour, except the regular blue ones, have been collected.
