Sister's got lots of pets--and what confusion that can cause! All the animals keep escaping; where can they be? The flaps hold the key! The rabbit's run away; perhaps he's hiding in the drawer. Doggie loves to chew things. Oh no, he's chomping on Dad's slippers. (And the four mice have scrambled inside his jacket.) Kitty's playing hide and seek; maybe she's snuggled in the laundry basket? Check and see. Looking after all those pets is so much work for Sister that she's gone somewhere quiet, too. And finding her is the biggest challenge of all.
