Press and hold the left mouse button to place the scraper and aim it by dragging the mouse around, release the left mouse button to fire the scraper. Some barnacles have more HP and require the scraper to move a farther distance to destroy them in one hit!

Calm Grandpa down by holding the left mouse button and gently caressing his head. Doing so will drain a bar that recovers over time. If the bar is empty you can't caress his head.

Hit R to restart the game.

Make Grandpa proud!!
