Max may be mighty small ...but he also has a mighty BIG secret. Max is a superhero! So when he spots the circus clowns stealing bars of gold from the bank, there's only one thing he can do. Max leaps into action, crying, 'Baddie pants, beware!' and tracks the naughty clowns all the way back to their Big Top hide-out, where their boss, Mr Big, is waiting to fill his trunk with gold.
