Yellowstone Yeti: Case of the Gushless Geyser - Hardcover

by Craig Vroom (Author), Angela Matlashevsky (Illustrator)

What's going on at our favorite park?
Strange things are happening once it gets dark.

Wolves to the west. Elk to the east.
And lurking in shadows, an unruly beast
Who's wild, humongous, hairy, and sweaty.
Some folks have called it the Yellowstone Yeti

Olivia and "Jenny the Great" team up with the Yellowstone Park Rangers when Old Faithful stops erupting. Using their Super Bubbly Tracker to search for clues throughout the park, the girls discover more than a gushless geyser.

Can the Lucky Penny Detectives solve this national park mystery?
