There comes a point in every young mammoth\'s life when it\'s time to grow up a bit and join the Mammoth Academy.  Arabella loves school, but Oscar is finding it a little more difficult to get used to. Especially as he is accused of stealing the school\'s oranges. He is sure it was humans - the most dangerous animals in all of the Mammoth Lands!  With the help of his new friend Fox, who has decided not to wash for 2 months so his fur will begin to self-clean, Oscar sets out to prove that humans are in the valley and at the same time stumbles across more trouble than he\'d thought!
