He went from being a background character with a calmer demeanour and was depicted as the smartest guy in the park and a wise sage that lived with and took care of all the cats in the park. as the series went on and Mike Smith started becoming more prominent, he became more and more erratic to keep up with the whole scenarios that Julian and Ricky and it was a response to the anxiety his character was undergoing by association. However, his character got more annoying after Clattenburg left because Mike got onto the writing team and then made everyone stupid in comparison to Bubbles and how he was always the smart one and right about everything.
