You are the fish and you want your freedom back. Touch the bowl you’re in to tip it over into the bathtub (1/21). Take the PLUG from the bottom of the bathtub to drain the tub (1/22) but this will only move the sponge.
Put the plug you’re still holding in the boat. This will make it sink (1/23). Take the little ROCK (1/24) and put it in the boat (1/25). This will push the plug out and will cause the boat to surface again. Throw the rock on the fan on the left (1/26). You will now sail to the right to the right and when the boat hits the edge of the tub you can jump out and dive into the tube of the throne. On your way to freedom!
