And about the visuals, I don't know, it kind of came about like that. I had already created these trees before and I thought it was great to put them at the bottom of a sea empty of water, visually it pops even if it's is absurd. Because I'm in love with the forest (and flooded forests like mangroves!!)
And besides that I love creating cute characters haha.
I don't know if that answers your question :)
