None at all. Each snake is 3D-printed as one continuous piece, so it slithers, coils and poses straight out of the box — nothing to build, charge or lose.
Gradient and multi-color snakes are printed individually, so where the colors shift along the body varies from print to print. Yours will match the listed color family, but the exact placement is unique to your snake.
It's a solid one-piece print with no loose parts to detach. Based on the product details we suggest ages 3 and up, with adult supervision for younger toddlers.
They're printed in luminous material designed to soak up ordinary daylight or lamp light and give off a soft glow in the dark — no charging cable needed.
