Egg Bat蛋蝙蝠

Egg Bat is row 7 of the game's guilü table, with the element Metal. The battle screen reads (Shoot Fire!): it is weak to Fire.

It is on drop table 1, whose first weight gives all 64 rolls to nothing, so it never drops anything even though the table lists Shellfish Powder, Guilü Balls, and Men's Extract after it.
