"Toadal Dude" is a combination of "dude," "toad," and "total."
"Eleganfibio" is a combination of "elegante" (elegant) and "anfibio" (amphibian).
Toadal Dude is based on the youkaiōgama (Japanese: 大蝦蟇,ōgama lit. "giant toad"), which is also his Japanese name. An old toad that turned into a youkai, it grows larger and more dangerous with age: it can take residence in a house's crawlspace and make the inhabitants fall sick one after another. In the worst cases, it'll even possess people.
Ogama's appearance might also be based on the eponymous protagonist of Jiraiya Gōketsu Monogatari, a skilled ninja and noble bandit, who mastered frog summoning magic, similarly to another Yo-kai based on Orochimaru (Venoct#Origin).
Toadal Dude's "random" nicknames in Yo-kai Watch 2 are: Ribbert, Croakool, Toadster and Splash.
