Suffering from severe cold Taarak tries to get a leave, but Kanishk instead forces him to take extra classes. Dr.J out of (fake) compassion makes a potion to cure Taarak's cold. But the potion backfires and turns Taarak into a fire sneezer. Now Taarak is sneezing fire and destroying everything around him (kids' homework, school property, Kanishk's office).
