Turtle-Turtle and the wide, wide river / Jane and Will Hillenbrand.

Enhanced descriptions from Syndetics:

Whish! Whoosh! When the river rises, Turtle-Turtle needs his friends' help reaching higher ground in this epic, but ultimately reassuring, ode to friendship and resilience.

The rain pelted down, down, down
And the wide, wide river rose up, up, up
All around, all around.

When a storm strikes, most of the animals know what to do- Skiddaddle! But Turtle-Turtle doesn't realize he should swim away . . . until the water rises. Although he's scared to weather it on his own, he learns that he doesn't have to. Comforting companions Heron and Frog help Turtle-Turtle until-bit-by-bit, friend-by-friend-he finds the strength within himself to push onwards to safer shores.

Rich with rhythm and read-aloud potential, Turtle-Turtle and the Wide, Wide River is a perfect bedtime book that masterfully melds an epic adventure with a reassuring ending. Drawing on their years of shared experience teaching and creating picture books, Jane & Will Hillenbrand offer readers a celebration of friendship and a gentle reminder that, even when you're stuck on the stormiest seas, your loved ones will help you to stay afloat.
