850252 Johnny Thunder Key Chain is an Orient Expedition Key Chains set released in 2003. It includes the Mount Everest variation of Johnny Thunder minifigure attached to a key chain, and the LEGO logo printed on a white 2x2 tile. The minifigure parts can move, but cannot be taken apart, because a special glue is used.
- It is the same set as KC37 Johnny Thunder Key Chain.
