This is one of the challenges I give myself in creating that years parade float / Idea.
But you can easily adapt any of them to a Dolly mount, or get even more creative!
This Is Vampire Mickey, Originally I intended to be Inside the Inflatable, but I ran into safety issues
that I couldn't overcome and decided to tether and walk with him instead.
Step 1: The Build
and cut the back Seam, and glued velcro strips onto the open seam, to act as a quick exit
and keep the air in (duh) - I used the Blower that came with the inflatable and made a air pump
station mounted on the side, along with a 12V car battery, and a Power converter
(that gave me 6 hrs of operation)
