The Bin Weevils need your help! Lab's Critter Contraption is on the rampage round the Binscape, making critters left, right and centre. Can you help Tink and Clott find the machine and round up all the critters before they trash the entire Bin? This is an awesome doodle story book for Bin Weevils fans. The inside pages are printed black and slime green, with lots of space for you to get creative and finish off the pictures!
