When going for an easy 3 star for a level, you're going to want to make sure you have this following toy that I have drawn a red circle around. This toy will be very important for this exploit.


If you do not have this toy in the base roster as shown in the image above, you can purchase the toy for 5 coins by click the little blue box next to all the toys.


If the toy is unavailable in this option, you may need to purchase another toy first before getting the one needed to spawn in. If you do not own this toy at all, you will have to progress through the main story, until it becomes available in the shop where you can buy stickers, palettes, and toys in Rapoville.

You're going to want to place this toy somewhere that gives you good breathing room between you and the toy. What this toy does normally is when it spots you, it will begin to shoot 3 missiles at you. When this occurs, what you're supposed to do is perform a spin attack on the first missile (SHIFT key) and make sure it collides with the second missile that was following it.


When done correctly, both missiles will blow each other up, and the game awards you with 300 points!


When dealing with the last missile, simply jump on it to get 100 points. From there, rinse and repeat this process, until you reach the score needed for earning 3 stars. Finish up the level and you're done!

That's it! It's a very easy trick. I hope this helps for everyone who wants to unlock all the rewards from earning a 3 star rating or simply get the achievement that's tied to earning all the stars. Have a wonderful day!
