In advance: Make fondant cabins. Add 1/2 teaspoon Gum-Tex to 4 oz. fondant. Tint 1 oz. each orange, violet, yellow and green; roll out 1/8 in. thick. Use patterns to cut cabin, roof and easel in each color. Tint royal icing to match fondant. Use icing to attach roof to different color cabin, allowing 1/4 in. overlap; pipe tip 3 e-motion details. Let dry. Attach easel to back; let dry on cornstarch-dusted boards.
Tint portions of melted white candy orange, violet, yellow and green to match. Mold dessert shell boats, following instructions for mold. Chill until firm; unmold and trim edges as needed. Insert shells into outer mold; press in cereal treat mixture to just below top edge. Seal and level top with melted candy. Chill until firm; unmold. Attach cabin to boat with melted candy. Use craft knife to poke small holes through candy where animals will go. Insert Fun Pix, trimming as needed.
