Alternatively, Robbinyu can be freed from the Crank-a-kai with a Purple Coin or Special Coin within the past, as well as being freed from the Oni Crank-a-kai.
In Yo-kai Watch 2, a Robbinyu appeared during the second part of the Treasure Hunters series of Requests. After the player had defeated Duwheel and found the treasure hidden away in the Abandoned Tunnel in Mount Wildwood, Robbinyu appeared and InspiritedMark, making him snag the treasure and run off with it. After tracking him down, the player then fights Robbinyu, freeing Mark from the inspiriting. The event would shake the Treasure Hunters, thinking Robbinyu's interference was a curse placed on the treasure.
