Christmas Lights, Christmas Bells, and Otter Christmas Smells.

It's December, and Christmas is just around the corner. A mysterious, smelly cloud of gas has settled over Lotta's hometown.

Can Lotta Otter and Rob Otler clean the air before Christmas morning?

If they can't Santa won't visit the town on Christmas Eve. Lotta and Rob must work hard to save Christmas for the local people.

This is Lotta's second adventure.

In her first adventure, Lotta and Rob helped to renovate a local park using recycled materials.

In this adventure, Lotta and Rob are taking on air pollution and saving Christmas too.

Lotta Otter books are fun, absurd, rhyming stories for children that adults can enjoy too.

No matter what the challenge, Lotta and Rob never give up.
