"This is the rarest pebble in the universe!"
During a heat wave, the waterfall of Roaring Ravine has diminished to a trickle. The now-dry riverbed is full of beautiful pebbles called smoothies and rollies. Wembley finds the rarest pebble in the universe: a perfect blue rollie, the greatest gift one can give to a friend. Wembley gives it to Boober, who becomes reclusive, refusing to share it with anyone. His friends try to get him to come out of his hidey-hole and share, but the attempt fails.Gobo comes up with a plan to get Boober to share: Wembley will sneak into Boober's hidey-hole, disguised as one of his balls of laundry lint (because he's the only one small enough to pass for one), and bring the rollie to his friends. They will then throw a party, which will make Boober see how much fun it is share.
When Wembley reluctantly sneaks into Boober's hidey-hole, his sneeze—on account of his allergy to laundry lint—wakes up Boober, who is far from happy at having his hole invaded and still refuses to share the rollie. On top of that, Wembley sneezes again, making the rollie roll into a crack in the wall. Boober, trying to retrieve it, orders Wembley out. Wembley sadly leaves—just in time to see Boober's hidey-hole starting to cave in. He runs to get their friends.
Meanwhile, Boober, as the roof is about to collapse on him, realizes how selfish he's been and that friends are more important than things. Wembley gets back with the others, who rescue him in the nick of time. When the rollie unexpectedly rolls out, Boober gives it back to Wembley—who decides to share it with everyone.
