his tentacle toes had worked well on land, So Eddie decided to test his tentacle toes in the water.
Thankfully, he lived right near a small shore, near a uninhabited beach leading to a river mouth.
So Eddie changed into his bright red swimming trunks (with some difficulty due to his mongo-sized feet struggling to get through the leg holes), went outside, and waded into the ocean.
He didn't go too far out, just far enough to test his tentacle toes.
Holding his breath, he dives Underwater.
Eddie very quickly found out that in order to swim Underwater with tentacles for toes, he had to flick his tentacle toes like how an octopus would move it's tentacles to swim.
It took him some doing, and a few times of coming up to breathe, but he soon got into the swim of Swimming with tentacles for toes.
After a hour or so, he lay on the sandy shore for a rest.
