Things You'll Need
Instructions
Inflate the Scooby Doo toy slightly until its paws open up.
Place the tip of a small funnel into the air piece of the Scooby Doo toy. You will need a funnel with a thin tip to do this.
Pour sand into the funnel so that it flows into the Scooby Doo inflatable. Use 1/2 cup to one cup of sand to weigh down each paw. The amount will depend on the size of your inflatable.
Finish inflating Scooby Doo until it's fully blown up. The sand in the paws will weigh down the toy so that it will stand up. You may need to shake the toy a bit to distribute the sand evenly.
