Venonat is said to have evolved with a coat of thin, stiff hair that covers its entire body for protection. It possesses large eyes that never fail to spot even miniscule prey.
Venomoth's wings are covered in dust-like scales that vary in color depending on their toxic capability. Dark scales are poisonous, while lighter scales can cause paralysis. These scales are released when Venomoth flutters its wings and leak out poison once they make contact with the skin
Diglett lives in tunnels and caves under the earth, where it feeds on tree roots and vegetables. It is known to live in burrows left behind by Onix. It also sometimes lives in burrows near forests and has even been shown to live inside of trees. Diglett digs regularly through the earth at a shallow depth, leaving perfectly tilled soil in its wake.
