Summary (if you care about spoilers for children's books, skip to the next section)
A bear is walking along being a bear when he meets another bear. He's wary, but the other bear just wishes him a nice day and they keep going in the same direction, at a different pace, thinking different thoughts. They meet another bear and then another and they start to enjoy each other's company, though they are still just walking in the same direction. Then they meet another bear who is stuck in a tree and help him down. They talk and realise that, though they are all different, being together feels lovely and they walk off together, talking and learning things about each other.

I LOVE Catherine Rayner's distinctive style
Fun factor
More aww than haha.
Is it supposed to teach children something?
Be open to friendship, even with people who are different from you. They might like you and you might like them.
Bottom line
Very sweet.
