The cave and other stories

Bear and Bird are best friends! And while they don't always understand each other, they both agree: all they want is to make the other happy. So, when neither of them can remember why they've circled today in red in the calendar, they each think they've missed the other's birthday and scramble to surprise each other with a party! And when Bear accidentally loses the ball while playing Boing Boing, he has to summon up all his courage to go into the Creepy Cave to get it back.
