Abstract
I focused on playing with toys. Then I found that there are very few toys used on snow. Investigation of the precedent case showed that playing with tools on snow was performed only under limited circumstances. I propose a toy that can do activity similar to caster board even on snow.
I made several prototypes and miniature models to reproduce the movements done on caster board even on snow, actually carried on the snow and verified it.
In the last prototype I were able to reproduce a movement similar to caster board on snow.
It can be said that it is possible to produce a mobility toy that can get propulsive force on the snow on its own.
