Voltorb (#100)
Peppermint candy.
Electrode (#101)
It would have a light flavor, sort of like a jawbreaker, except unlike a jawbreaker, there's a good chance that if you bite down too hard it will literally explode and rip your jaw off your face.
Exeggute (#102)
Rotten eggs. We mean, that's... what they are, right?
Exeggutor (#103)
Only Exeggutor's face would be edible, and it would taste somewhat coconuty.
Cubone (#104)
Soft, tender dinosaur meat marinated in cold, salty tears and served in a skull. Better for appetizers.
Marowak (#105)
Similar to Cubone, but less of a wuss.
Hitmonlee (#106)
Chopped liver.
Hitmonchan (#107)
Pork chops.
Lickitung (#108)
Cow tongue.
Koffing (#109)
Cigarettes.
Kids, let's have a talk. We know that movies and television shows make eating Koffing look "hip" and "cool," but it's not. The Surgeon General warns that there's a direct correlation between eating Koffing and contracting lung disorders such as cancer, emphysema, and other respiratory problems.
