This is a design that combines a BallRun pack, a Ferris wheel pack, and Basic pack.

• BallRun pack: Connecting squares and Short straight Tubes.
• Ferris wheel pack: Hexagon.
• Basic pack: Square and Equilateral triangle.

If there's no hexagon available, you can also use an equilateral triangle as a substitute

The round body of the rocking guitar does indeed resemble a cat, doesn't it? 😄
