Alphabet Drops

I'm sure I'm not the only one looking to get an idea of which monsters drop each letter so I figured a thread would be very helpful for finding those last elusive letters. So if anyone can post which monsters they've seen dropping letters that would be great

A - Cold Eye
E - Cold Eye
I - Zombie Lupin
L - Zombie Lupin
M - Jr. Sentinel
N - Curse Eye
O - Curse Eye
P - Roid
R - Roid
S -
T - Rumo
W -
X - Cube Slime, Golem
Y - Neo Huroid
Z -







Also I had to look up how to spell alphabet because I kept thinking alphabits. Cereal has ruined me forever.
