So far, the animals in the game can be taken home and put in your backyard. Where would you put a manatee?
Anyway, you milk butterflys. you nibble pigs. you squeeze chickens. what's needed here is a different verb. Perhaps you hug manatees. Or tickle them. Then what do you get? Manatee oil?
OK, fine, whales, but only if they are floating in the sky.
Saishuu Shiken Kujira, Final Examination Kujira, 試験最終くじら (Japanese).
"A newly arrived teenage boy is astounded to see a whale floating in the sky above a city. What's just as astonishing is that a cute girl finds his reaction amusing. Of course there's a whale in the sky--what did this foolish boy expect?"
