Patrick the party-hater

Balloons? Sausages on sticks? An entertainer? Oh NO! It must be a party . . .

Patrick loves making models and creating his own inventions. He does not love Musical Bumps, big crowds and having to be jolly. But his mum is convinced that going to parties is good for him. She even wants him to have one of his own. Surely there must be a better idea?
