Dedos

Verde Dedos (commonly referred to simply as Dedos) was an early version of Leafos, present in development builds of Viva Piñata.

Trivia

Dedos' name is Spanish for "green fingers", albeit grammatically incorrect. Because adjectives in Spanish come after nouns (and are pluralized when modifying a plural noun), the correct translation would be dedos verdes.
In the game files, Leafos is still referred to as Dedos, indicating that her final name was decided late into development, or perhaps the old name just stuck.
