Both this card's Japanese and English names have puns: in English, it comes from "Des Frog", with the "e" replaced with a 3, as it is a "triple" "Des Frog"; In Japanese, it literally means "3 Death (Des) Frogs", but it's read as "I'm Mr. Frog" (Gaeru-san desu).
The 3 in this card's English name is an example of Leet Speak.
Three "Treeborn Frogs" and Three "Des Frogs" appear in this card's artwork.
This monster has the Chinese character for "ultimate" on its arm. This is understandable, since "D.3.S. Frog" is the strongest monster in the Frog archetype in terms of ATK.
