Gator's real name is Gerald but because he looks like an alligator the engines of Sodor decided to nickname him 'Gator'. He works high up in the mountains and is extremely brave and adventurous. The 'Take n Play' Thomas range is made up of durable die-cast engines and plastic track, please note it is NOT COMPATIBLE WITH ANY WOODEN RAILWAY SYSTEMS (or with with Hornby Thomas the Tank Engine, Trackmaster Thomas, or with Mega Bloks Thomas). Though if you still have any of the 'Take Along Thomas' range (or if you've picked up some through hand-me-downs etc.) the take n play engines etc. are compatible. SUITABLE FOR CHILDREN AGED 3 YEARS AND UP.
