Welcome to Big Sky Mountain: a home for everyone! Life never stays still for long on Big Sky Mountain. Rosa and Grandma Nan are off on an adventure to Toe-Dipper Bay, to see who’s in trouble – a distress flare has gone up!

When they arrive they find the beach covered in plastic rubbish, and a family of beach otters farming seaweed, while doing their best to tidy up. Rosa and Grandma Nan join in, but they have to find out who sent the distress flare – because who is that wrecked out at sea? Rosa and Grandma Nan will need the otters’ help to build a raft to get to them…

An action-packed story featuring curious otters, wise hermit crabs and peckish puffins, which addresses pollution and recycling in a gentle and friendly way for young children.
