This is a mind reading hippo How to use: Click the green flag. Then, choose a whole number from 0 to 99. Whatever number you want! Next, add the digits from your number together. Subtract the total from the original number. Lastly, remember the letter next to your final number. Then click the hippo! For example: Let's say you picked 11. 1 + 1 = 2. Then you would do 11 - 2. That's 9. You would remember the letter next to 9 and click the hippo.
