Rocky, a crane from the Thomas & Friends series, is a very strong crane who is used as a rescue and maintenance unit. Rocky is a valued addition to the Island of Sodor, as he can pick up other engines and heavy loads that Harvey can't, but is also a gentle giant who wants to be everyone's best friend. Although useful in any situation, Rocky can only move when there is an engine available to pull him, as observed by Gordon and Edward, seen in the "Edward Strikes Out" story. This version of Rocky is wooden. Compatible with the Thomas Wooden Railway, BRIO, Lionel Express Track and most other wooden railway systems.
