Furius Baco for me - barrel themed trains...a monkey assistant...bucket-headed robots...and the ride itself which constantly WACKS your head in!
(pun war anyone?)
I remember going on Professor Burp's Bubbleworks for the first (and only) time at the age of 5...coming off one terrified lad...and not returning to it until the Imperial Leather retheme! ...
...QUACK!
I remember on the day I finished my SATs back in Year 6 (...and now I've just remembered I've only just finished GCSEs! ) I went to Thorpe with a couple of my friends straight after school! Complete ghosttown!
