Shellder (#90)
Clam, except a clam that judges you as you pry open its shell and scoop out its salty innards.
Cloyster (#91)
All the taste of the oyster with all of the awkwardness of a lobster's cold, dead eyes staring at you while you try to eat it.
Ghastly (#92)
Black licorice.
Haunter (#93)
Fennel.
Gengar (#94)
Absinthe, but unlike regular absinthe it's impossible to sweeten or water down. Pour it through sugar cubes all you want - it's still going to be the most bitter thing ever.
Onix (#95)
Rocks. Literally rocks - there's no meat in this guy.
Drowzee (#96)
Chocolate-covered banana. Seriously, you guys, Drowzee taste SO GOOD.
Hypno (#97)
Also fairly delicious, Hypno would have a banana taste topped with some whipped cream. It even comes with its own doughnut!
Krabby (#98)
Crab. Just... regular crab.
Kingler (#99)
King crab.
