Be Careful! Pretending you are something you are not can get you into trouble. Derek, an asthmatic boy from the city comes to Habitat for a weekend visit. He hates telling other kids he has asthma, because they always treat him differently when they find out. Lou goes to a popular girls party and tries to dress for the occasion, but it backfires! Derek is almost discovered by Jerry using his inhaler, and to avoid detection, throws it into the bush where it goes down a snake hole. When he needs his inhaler, with Skippy's help they find where the inhaler is and are able to retrieve it when Lou bravely puts her hand into the hole!
