Sammy Feral's Diaries of Weird: Yeti Rescue (Electronic book text, Digital original)

Sammy's back for another weird adventure
Ever since Sammy discovered that there are crazier animals in the world than just lemurs and lions, his life has become pretty weird. So when a Mongolian Death Worm turns up at his zoo, he's not that surprised. The Death Worm needs help: his best friend, Bert the Yeti Chief, has gone missing.
Can Sammy summon the Ministry of Yetis and rescue Bert? He's going to need help from his old friends Donny and Red, not to mention a very reluctant Wish Frog...
An action-packed adventure for the Wimpy Kid generation.
