The next day he brought a home made chip sandwhich to school where the science teacher, a Slitheen in disguise, had a negative reaction to the vinegar in the sandwich as vinegar is the Raxacoricofallapatorian's weakness. After school his science teacher unmasked and chased Maria and he bumped into Clyde, Clyde sprayed deoderant to confuse the advanced sence of smell of the Raxacoricofallapatorian. After meeting Sarah Jane Smith he helped defeat the Slitheen. (SJA: Revenge of the Slitheen)
