Kavi's Three Baby Mystery
Kavi finds three little eggs 🥚🥚🥚. "Which babies are hiding inside?" One egg holds a wriggly caterpillar 🐛 that will become a butterfly 🦋. One holds a fluffy chick 🐣 that will grow into a hen 🐔. One holds a swimming tadpole that will turn into a frog 🐸! "Three eggs, three different journeys," hoots Kavi. "Let's compare them!"
