When (low density) gas is released, the overall density of the manatee is increased (more volume is from the high density meat and fat bits instead if the low density gaseous bits) so the manatee sinks. Then, through digestion and such, gas inside manatee can increase, making its overall density lower and it floats. (Kind of like how ships float even though their made of metal, since the majority of the vessel is air, the overall density is less than water)

This is also how submarines sink and resurface I think, but they release and let in water.

idk I was just guessing. I don’t see how the joke with ecological conservation (since getting rid of invasive species is good, right?)

I am assuming “conservation areas” in this sense means native/indigenous lands

edit: Whoops I am wrong. Ecological conservation then. I thought invasive species were bad for those?

I am assuming because a) Japanese, as the other person said and b) Gundam is where robots in the future fight bad guys, right? So the invasive chestnut species is the bad guy, therefore Gundam

Also maybe Gundam has time travel, idk. I haven’t watched it so I’m pulling this from thin air. I just know Gundam has cool fighting robots

I’ve got Asperger’s (pronounced “asburgers”, not “aspurrgers”), not ADHD!

pretty sure they face forwards. That’s what Minecraft ones look like, anyway, and a quick search of real ones look like they have forward-facing eyes
