So this is base on real animal?

There’s not really any conclusive evidence showing it’s true but some people theorized that dolphins play with pufferfish toxins get high off the toxins they release, so a pretty similar premise

Its not a theory tho

we don't actually know what's going on and why they're playing with the pufferfish because nobody's got a dolphin on TTX and then given it an mri or something yet. too expensive and yknow how research funding is doing in most countries lmao. TTX also doesn't get you "high" or anything similar, it's a paralytic

for all we know it could just be the dolphins being pieces of shit and then getting kinda poisoned. that family of animals are always doing a bunch of weird shit (see the orca salmon hats). there's also not a whole lot of evidence it happens a lot, basically just that one BBC clip from what i could find

however, it makes for a "fun" analogy for the story!!! which is the important part here
