Too many toys!

"Ever since Lulu was a little baby, she has had Jupiter--her lovely, cuddly, most-favorite-ever teddy bear. But with each new birthday, she gets new toys. And with every passing Christmas, more new toys. Very soon, Lulu can barely fit in her own bed, and poor Jupiter feels very left out. Lulu simply has too many toys! So she decides to throw a very special party--a party for all her toys and all her friends!"--Dust jacket flap.
