DS1 has asked for a dumper truck cake for his birthday party on sat - HELP!

[mabel1973]

I have done a tractor and a car...but this is a challenge!
Any ideas???
Thanks

Make a chocolate cake and decorate it as a building site. Buy a toy digger and place it digging holes in the choclate icing.

V good thinking!
and much easier than attempting to fashion a dumper truck out of a victoria sponge and some swiss roll!
