Mr Bentley is in need of a proper Mayor's office so he can stop filing his paperwork in Mrs Bentley's greenhouse. Bob sets about constructing a special earthship out of unusual recycled materials. Sumsy wants to help and sets off to find some materials for Bob. Unfortunately, she gets the wrong end of the stick and brings some bricks and some glass from Mr Bentley's greenhouse - things that people still need. Chaos ensues when birds make off with Mr Bentley's paperwork. Spud retrieves the paperwork back but Sumsy feels terrible. Eventually Sumsy has a great idea for some unusual office furniture, woven from recycled wooden twigs - including a filing cabinet for Mr Bentley's paperwork!
