Even though everybody cucked you out because of your invalid statement but let's me remind you that Bulbasaur line, according to Masuda is the most Pokemon-ish looking pokemon and it existence is an example of animal and plants living together.
You can say it was a failed experiment, but Bulbasaur line do gets bigger, they grow up, their evolving make more sense than anything else but that was the purpose of the line, to be a showcase of what pokemon has to offer between of 2 species. And interestingly enough, Bulbasaur line is the only starter than is based on multiple species rather than 1.
Now we have cats and pigs that turn into wrestlers, seals turn into clowns, Foxes turn into wizards, birds and fishes turn into entirely different species, etc.. which is extremely silly and sometimes cringeworthy.
Not sure about you, but Venusaur line evolution is much more better and make more sense than most of pokemon now, it just took long time to appreciate the line and its concept.
