Need a Large Variety of Models

Need a Large Variety of Models

I'm making a preschool wars and I need some simple models. Here is a list:

Sand Castle - needs to look like a castle made out of sand.
Sand Tower - a tower of sand
Mud Tower - a tower of mud
Stone Tower - a tower of stone blocks
Lego Figure - a Lego figure, needs to look like a real one in a Lego set
Box of Firecrackers - a box with firecrackers sticking out
Spray Can - looks like a small spray can

I will delete ones from the list when I have a nice looking model for them.
