What Pokemon are based on frogs?

Question

Greninja maybe? Who else?

Answer 1

-Bulbasaur and its evolutional line
-Poliwag's evolutional line which are based on frog spawns, and politoed which is a frog
-Croagunk and its evolution
-Tympole and its evolutional line

source: pokedex and logic

PS:These are the ones plus froakie's evolutional line which you partialy mentioned.

Comments

Bulbasaur and its evolutional line is not a frog.

---

Bulbasaur are supposed be dinosaurs.

You also missed the Greninja line.

---

Bulbasaur and its evolutions are  frogs more and less dinosaurs.Also I mentioned the froakie's evolutional line look at the end

1. "Bulbasaur is a portmanteau of the words bulb (a rounded underground storage organ present in some plants, notably those of the lily family) and the Greek saur (lizard)."
2. I'm blind ignore that.

So basically its a Lily Lizard
XD jks

Answer 2

Here is an up-to-date answer for gen 9 (:
-Bulbasaur line
-Poliwag line
-Croagunk line
-Tympole line
-Froakie line
-Tadbulb line

maybe
These Pokémon might be frogs although there is not enough proof for them to be on the main list.
-Heatran (resembles frog)
-Toxel line (could be based off a poison dart frog)

Source 2: the database’s Pokédex!
Hope I helped!

Heatran is apparently not officially a frog, but it does have froggy aspects. It is described as the lava dome pokemon and is not in any way mentioned to be a frog in any of its dex entries(I deffo didnt need to frantically google this and am not at all worried about it going on my search history permanantly.)

Have a hard time believing that Toxel/Toxtricity have anything to do with frogs, as they're clearly salamanders or lizards, which can also be poisonous, and have no inherently froglike qualities, while all other Pokemon that are based on frogs DO have some sort of froglike quality. Heatran is also a huge stretch. It's vaguely frog shaped but I think that's just because it's a quadruped with short legs; if you're going to define Heatran as a frog, I think you should also put Avalugg and Metagross on the list, as they're froglike in the same ways that Heatran is. I'd be more inclined to agree with the assessment that it's a frog if it had froglike hind legs, though it doesn't.

I usually don't take Bulbapedia's origin and biology section for certain because of how debatable it has to be, but it just says Toxel might be based on a poison dart frog because of its typing and that it secretes poison. Therefore, I argue Grimer is a boxfish.
I think it makes sense to separate Pokémon that are based on frogs for sure, and those that might be from one another, in the answer.

^^^
There are poison lizards, why wouldn't it be based on that? Just because two things are true independently doesn't mean that they're linked.

If it will end the debate, I will separate heatran and toxtricity from the others as  a “maybe”
