There's a strange smell in the garden and Wussywat doesn't like it, so he tries to find out what it is. First he encounters Ortus in his herb garden. His herbs smell nice. Then Oggy takes him on a sniff chase only to find loads of nice smelling flowers. Next, he and Duckadile discover Ird's newly baked cakes - but they are too yummy to smell bad. Then Wussywat discovers the compost heap which is really, really stinky! Wussywat has the idea to take some of the nice smelling things and put them around the stinky thing. What a clever cat!

Wussywat finds a sofa in the garden and starts jumping on it. He finds some bats under the cushions and a squeaky ball so they play squeaky tennis. In the process, Wussywat manages to mess up Ird's jigsaw of a boat so she has to start again. Wussywat likes the jigsaw so asks Ortus if he has any more in the shed. He doesn't but he does have lots of other things, including a rubber ring that Duckadile starts to play pretend with. Wussywat has the idea to make a pretend jigsaw and uses the different objects to make a boat out of the sofa. What a clever cat!
