According to Rashi, the Plague of Frogs during Passover "was only one frog, but when they struck at it, it was split into many swarms."
So if you want a biblically accurate Seder, I suggest you get a frog piñata and fill it with frog shaped candies.
@LilahTovMoon So the moral of the story is not to commit animal abuse? I can live with that. 🐸
