Mario Haunted House 3, where is the fourth floor gem?

The first gem is in the helicopter model on the left side of the elevator. The model needs to be sucked down by a vacuum cleaner. The second gem is behind the camera model, and you need to pull the film in front to open the mechanism. The third gem is under the carpet in front of the studio. You need to vacuum the carpet. The fourth gem is in the bottle in studio 4. The fifth jewel is above the front of the bicycle in Studio 3. Jumping can scare away jewelry monsters. The last gem is on the BOSS, so you need to be in two places to get up from the scissor lift car in front of Studio 3. Gems are frozen and need fire to thaw.
