Kavi and the Case of the Moving Clip
Kavi finds a metal paperclip that slid across the desk all by itself 🔍. "Nobody touched it... so who moved it?" Kavi puts on a detective hat. "A detective never guesses. I collect clues, cross off what can't be true, and the one answer left standing is the truth. Let's solve it together!"
