*How it works:*

1. *Stack*: Each piece is a colorful, egg-shaped shell with wavy edges. Babies stack them big-to-small on the blue base. 

2. *Wobble*: The curved bottoms + zig-zag edges make every tower wobble, tilt, and roll instead of falling straight. 

3. *Nest*: The pieces also fit inside each other, so kids can nest, sort by size/color, or just roll them around.

*What kids learn:*

- *Balance & cause-effect*: “If I stack it like this, it wobbles. If I do it like that, it falls”

- *Fine motor skills*: Grasping, placing, nesting the 7 pieces 

- *Problem solving*: There’s no wrong way, so they test what works

- *Colors + size*: Gradient colors help with sorting from big to small

*Age*: 6m+ per the packaging. The pieces are big, soft-edged, and safe for mouthing.

Best part: No instructions needed. Kids figure out their own “game” - tallest tower, wobble challenge, knock-it-down, etc.
