Thank you for playing and providing feedback! There is a mechanic that prevents you from eating something "too big" for you. That's definitely something we could improve, enabling the player to read more easily if they can eat or not an item. You can find smaller items to eat somewhere for sure. Some items are hidden and are required to be able to eat the bonus. You might be able to find a way to go further down the level and come back, but that was not the intended path.
