High up on a mountain live three billy goats Gruff. Having eaten all the
grass in their field, they set off in search of pastures new. Across a
river is the richest, greenest meadow they have ever seen - but in order
to reach it, they must cross a wooden bridge. The bridge is guarded by a
mean ugly troll, who gobbles up anyone who attempts to cross it! How
will the three billy goats Gruff avoid the same fate?
