These are the hardest to raise of all the Bandai pets.
Extremely needy, but really cute.
( Umi-no Tamagotchi)
On the market in March of '98
I have only had one grow in to adulthood.
They know they are being paused!! So if you do pause them, don't advance the time.
They need attention constantly, about every three minutes while they are a jellyfish.
All the attention was worth it when I saw that little fish swimming around my screen that first time. The only adult I ever got was the clam.
