The Big Red Thing

S2 E15: The Big Red Thing has come to terrorise Berk and friends once more. Luckily, Rogg is at hand and when he is swotted by the Big Red Thing he gets very cross and goes after it in retaliation. Berk, Boni, Drutt and his nippers, hurry after him out of the castle to make sure Rogg is not hurt. They see the two monsters fighting, but then the Big Red Thing disappears and Rogg is left motionless. They cannot rouse him and sadly realise that "Rogg has gone". Or has he? (After the credits) Rogg wakes up, but where is The Big Red Thing?
