Totally Super Squad! Book 2: Bad to the Bot
When Penny and George can’t convince the Super Squad to suit up and come out of retirement, the kids set out to rescue Nana on their own. They decide to sneak into the Super Vault to look for clues and end up uncovering a stash of busted '80s superhero gadgets—and a lesser-known member of the Squad who just might be willing to lend a robotic hand.
