The class needs a new mascot for their soccer team, the old mascot being so old that nobody even knows what it is anymore. Phoebe is convinced it should be the butterfly, but the rest of the class disagrees with this. Janet shows up again and convinces the class that their mascot should be the "Bog Beast." Since nobody seems to know what a bog beast is, the Friz takes the class on a trip to the swamp to find out.
