"The Casagrandes' family run mercado has been a staple in their bustling Great Lakes City neighborhood for years. But when the mercado's stock keeps mysteriously disappearing overnight, it seems that it's time for the mercado to close down. Why is all the broccoli soup missing? Who would ever take that? And how come all the regular customers look so tired? Then, join Carl on another scheme to embrace his infant side as he joins a baby competition. And, when things go bump in the night, it is up to Ronnie Anne, Carl, and CJ to get to the bottom of it. PLUS: Ronnie Anne tries to get Carl tickets to the El Falcon Convention. But she's out of luck when the tickets sell out in seconds! Could the path to the convention tickets lead the Casagrandes to Royal Woods?"-- Provided by publisher.
