Also, if you use Release (Spit Out by some translations), you release what's in your mouth, and it does base damage according to how many times you used Eat *100. So theoretically, you could have a 300 power Normal attack. I'm not really sure what the cap is, but its probably 300.
So does this take-up three move slots?
