There is a space whale in the original Star Fox on SNES too (along with a couple other creatures, notably space rays).
Also there are three named sky whales in the Legend of Zelda canon. Some think the whale fossils in Breath of the Wild/Tears of the Kingdom could be them. It’d be a bit dark.
Also that one episode of Futurama.
And Star Trek (multiple types actually)
