Tattie & Morag

Tattie thinks he knows everything. Morag knows better.

Tattie is an otter with a calculator, a pencil behind his ear and total confidence. Morag is a puffin with round glasses, a tartan bow tie and very little patience. Together they live in a wee Scottish harbour town and get revision spectacularly wrong, then right.
