How do I make battery powered sound effect device?

I'm making my son a monster truck. Yes, I will post pics and a description of the build when finished.
I want my son to press a button and for loud VROOM VROOM noises to spew forth.
I've looked into audio greeting cards, but I don't believe they are loud enough. There are ways of increasing the volume of them (adding a plastic shot glass I hear works well), but I still don't think that would be loud enough to satisfy my monster boy.
The vital elements:
Have to be able to add my own sound (vroom).
Have to be able to initiate that sound clip by pushing a button (from radio shack).
Have to be portable (fit into the car)
Has to have a replaceable power source (C cell batteries?)
Has to be loud (loud enough to satisfy a kid)
volume control is a bonus.
multiple sounds tied to multiple buttons are also a bonus.
Lastly, and sadly, it must be cheep. I'd like to keep the project under $20.
Thanks in advance mefi peoples!
