Not much is known about Izzy, other than that Lana owns him as a pet. He tends to scurry around the house, as evidenced when Lincoln looked for a quiet place to read comics in his underwear. The only known fact about Izzy is that he seems to have replaced Lana's former pet frog, Seymour.
Izzy is a small green platynote lizard, with a long tail, some spots, and a sharp tongue.
In the Polish dub, her name is "Szczurka" from "Jaszczurka", which means "Lizard", and the literal translation of "Szczurka" would be "Zard".
Izzy is a female in the Polish dub. However, in the U.S version, Izzy is a male.
Izzy is a female in the Hebrew dub as well. However, unlike the Polish dub, he keeps his original name.
