Fiona the hippo (Picture books)

When a kookaburra named Matilda feels down, Fiona and the other zoo animals dress up to cheer her up.

It is Fiona's birthday, and fans from all over the world are sending her cards and gifts, she is giving interviews and having her picture taken, and with all the fuss she is neglecting her zoo friends--and when her mother points this out she decides to throw her own party, with gifts for all her animal friends.
