Brother Pig is a piglet who is best friends with Kipper, Tiger and Jake. He has a little cousin named Arnold, whom did not appear until "Pig's Cousin". He speaks with a Brummie accent. He is voiced by Chris Lang.
Pig is fun and curious, but he can be greedy, clumsy and overconfident at times, but, mostly he is temperamental and sensible and he does not hold a grudge. Pig loves chocolate cake and biscuits. He is often seen eating more than his fair share.
