Great Uncle David and Malcolm visit

Great Uncle David and Malcolm stopped over on their way to Hawaii to celebrate David's birthday with us.
It's his birthday but he gave me a present! Malcolm watches me closely as I rip the paper. I wonder what it is?
Whoah!
It's a bulldozer!
I'm showing Malcolm how it works.
I'm keeping the bulldozer far away from David...just in case.
Sparklies! Happy birthday!
All done. Time to blow out the candles.
