My Mom Is Out Of Town And I Wanna Do Something Nice?

So my mom left for Egypt and the house is a mess!!! Really, I thinking of cleaning the house, but I won't have enough time. She's coming Home on the 21st at 12:00 A.M. but thats not far from now and I am limited time at my house because every few days my uncle picks me up to go to my house and take care of the animals and the plants. Since I can't stay at my house alone for two weeks my Mom had me stay at my Great-Grandma's house. I really wanna do something nice without her getting all AWWW and Gushy on me I HATE IT!! IT DRIVES ME NUTS!! So please have any other ideas encase I can't finish cleaning the house?
