It's Happy Heart Day at school, and all the kids are doing stuff to raise money for charity. Of course, charity begins at home as far as Josh is concerned, and he's got a money making scheme on the go that could earn him a fortune – or lose him one – selling alien-made flippers to the participants of the sponsored swim. Mel's contribution to the fundraising is to take part in the school sponsored-run. Only she's less interested in getting sponsors than she is in planning who she's going to run with. Trent thinks it's going to be him, only Mel decides to drop him for a boy she fancies. So Trent finds a fanciable partner of his own. Meanwhile, when Lucy wants Brian's help on her magic act, his ambitions don't stop at just being her assistant and things rapidly begin to get out of hand. He almost humiliates her in front of all her friends, but then saves the day with some clever morphing and makes her act a roaring success.
