Sure, let's break the scene down into simpler steps:

1. **Background:** Start with a blank canvas. The background should be pure white.

2. **Clownfish:** Next, you're going to draw an orange clownfish. But this isn't just any clownfish - it's a cute and exaggerated version. Think of it as a cartoon clownfish. Its eyes are very large, almost filling up its whole face, with tiny pupils in the center. Its mouth is open wide in surprise.

3. **Cube:** Now, in the clownfish's fins, it's hugging a cube. This cube is a 30x30cm square in size. It's not just any cube, it's a control point for something. This could be represented as a small dot or symbol on the cube.

4. **Cube Faces:** Each face of the cube is made up of two triangles. One triangle is white, and the other is orange. They fit together to form the square face of the cube.

5. **Action:** Finally, add some dynamism to the scene. The clownfish isn't just floating there - it's leaping out from the water surface, hugging the cube.
