Dexter had tried to excuse himself out of P.E. (with a fake note), but the new coach does not buy it, so Dexter is forced to play dodgeball, fed up with losing, Dexter builds an exo suit to help him win, but is ironically hit with a dodgeball by Dee Dee. This episode is clearly inspired by the film Aliens, as the exo suit that Dexter wears is almost identical to the loader Ripley uses against the Queen.
