"Sometimes, things are exactly what they seem!"
- Use a Flying Creature to fly directly under the Starite, then place an object (Rock, Brick, Crate, etc.) on the Red Button
If you're having trouble with that solution, you can attach a Net (standard) to the right spike and the spike directly under the Starite to cause it to bounce off to the left.
You can also use a Battery to fry the Shark in the water.
