Froggy
Every week, one of the student in Yoshi's class would get their turn to take Froggy home for a weekend. It also comes with froggy game, book, journal.... Yoshi took Froggy everywhere. At the end, the parent would write a journal about what Froggy did with the kid, which would be told by the teacher in the class. The funny part, I asked Yoshi what language does Froggy speak, he said "English". (but he was talking to it in all sorts of language though...)
