But what about Dunsparce?
Excerpt for Wikipedia: Dunsparce (ノコッチ, Nokocchi?) is a land snake based on the tsuchinoko, a legendary snake-like cryptid from Japan. It has a yellow hourglass shaped body, two tiny wings on its sides, a drill for a tail,[23] and two spikes under its chin. Its underbelly is blue, as well as the markings on its back. Dunsparce lives in caves[24] and deep underground in nests of complex design.[23] Its rudimentary wings enable it to hover just above the ground,[25] providing it with an alternate method of motion besides crawling. Despite these wings and bug-like appearance, Dunsparce is solely a normal type Pokémon.
And there's no scarcity of that during outbreaks.
I think Lugia is based more off the moon and Ho-oh represents the sun.
But some really common Pokemon are based off cryptids, too.
Ditto is based off a globster (unidentifiable piece of carcass that looks like a giant blob.)
