Talking about making the 4th world of So Many Me... It’s kinda traditional to me for a traditional platformer from the SNES day with light-heart theme like Kirby or Super Mario Bros. will have an environment in the sky with fluffy mellow cloud platform and those giant bean plant lurking around. Basically I think they’re all inspired from Jack and the Giant bean blah blah bed time tale from our childhood. Source: http://www.moddb.com/news/devlog-voice-from-the-artists-cave
