The Skyworthy allows the player to travel to both a Shipwrecked or vanilla/Reign of Giants world. It may be crafted again to travel back to the Hamlet world. In Shipwrecked or vanilla/Reign of Giants worlds, the required Can of Silly String may be found by hammering a Wicker Basket which is generated somewhere in the world. Can of Silly String can also be obtained in the Royal Gallery . Once traveled to a different world, the player can also find/craft the Seaworthy to use for travel between Shipwrecked and Reign of Giants worlds.
A Skyworthy tends to prioritize linking to another Skyworthy in another connected world (the same appies to the Seaworthy). With this mechanism, a player can utilize it for quick travel in a Hamlet-compatible world. For example, with a Hamlet-compatible Shipwrecked world, the player can build a Skyworthy in their main base and then build a Seaworthy near a Slot Machine in a different island. To quick travel to the Slot Machine the player must have a connected vanilla/Reign of Giants (RoG) world with a Skyworthy and a Seaworthy built next to each other (the player must obtain the Sea Worther and the Can of Silly String to craft them). Use the Skyworthy to go to the vanilla/RoG world, then use the Seaworthy, and upon entering the Shipwrecked world the player would be on the Slot Machine Island.
