In Wonderland Adventures he or she is in The Foggy Mountains and finds the blue Rainbow Shard and puts it in a safe which can only be opened with the right combination. He or she typically forgets the combination but has written it on signs scattered across The Foggy Mountains which the player has to find to unlock the safe to collect the blue rainbow shard.
In Mysteries of Fire Island he or she is in the camp and purchases a Memory Gem from Persniffoni then puts it somewhere then forgets where it is. The player then receives a piece of map from Gaboonga then finds his or her memory gem then Gaboonga remembers where his or her other piece of map is and gives it to the player.
