Building a snowman animal crossing is quite simple. All you need is a snowy area, some snowballs, and some decorations. Start by rolling up a small snowball and placing it on the ground, then roll up a medium-sized snowball and place it on top of the small one. Next, roll up a large snowball and place it on top of the medium one. Now you've got your basic snowman structure. To add decorations, simply place items like hats, scarves, and other accessories around the snowman.
