So now my younger daughter is bitten by the Sea Monkey bug. I've been through this before. The good folk at Sea Monkeys Inc. have upped the ante, however, and offer various theme packages now. There's Space Shuttle Expedition, for instance, and Sea Monkeys on Mars. I believe Skeeter is torn between the Magic Castle and the Ghostly Galleon. There are ten more, by the way.
When I was a senior in high school, my AP Biology teacher made us enter a Science Fair exhibit. As a senior! I was enraged, and bought some Sea Monkeys and put up a cheap triptych called "The Life Cycle of the Brine Shrimp" (actually, I think I recycled my brother's triptych from his 5th grade science project called "The Life Cycle of the Brine Shrimp"). The brine shrimp were new, however. Absolutely the worst academic work of my life. He gave me a C, and it lowered my grade to a 79. I was kept out of the National Honor Society by 1 point in one class on 4 years of high school achievement.
You could say I have issues with Sea Monkeys.
