Spy Penguins

In this hilarious second novel in Sam Hay's action packed illustrated chapter book series, Spy Penguins, two young adventure-loving and gadget-obsessed penguins must prove their favorite uncle is innocent before the Frosty Bureau of Investigation locks him away forever!
Jackson and Quigley were this close to joining the FBI (Frosty Bureau of Investigation), until Jackson's mom found out and they ended up scrubbing seagull poop instead. At least they have Uncle Bryn's birthday party to look forward to. But when they get to the Ice Cream parlor, the FBI agents are acting strange. Instead of talking, Uncle Bryn and his friends just finish their glowing green ice cream, then jump into a waiting ice cream truck and disappear.
It's obvious that something has gone very, very wrong, and now Uncle Bryn is suspected of being a master thief! Can Jackson and Quigley solve the case before Uncle Bryn is locked away forever?
"Chock full of penguin-themed wordplay, ... This light, funny adventure series will appeal to elementary school mystery fans." —School Library Journal on Spy Penguins
