Mr Fatty is hungry... hungry for speshool sushi math numbers things. It's ur task to feed this guy... feed him good... feed him lots... and the only way to do it right is to answer math questions.
Answer correctly and Mr Fatty will get fatter and more happy. Fail to answer correctly and lunch is over for Mr Fatty. That will not be good. Mr Fatty needs to eat.
Are you any good at simmple maths? Hope so. The weight of someone very important is now in ur hands.
