The Ghost That Barked

CLUES
an old steamer trunk
a howling beast
roasted garlic meatballs

Scooter Spies Max, Oscar, and Lily (and her pet chameleon, Speck) are up to their necks in mud in their latest case, The Ghost That Barked. While practicing their moves at a construction site, the scooter riders uncover a mysterious old steamer trunk -- and hear a wild howl in the night
A blue paw print leads the three friends directly into a daring museum escape, a secret scooter ride across town, and smack into a giant mountain of goopy, gloppy mud!
