In front of a fountain

Her:� Look Mummy, a marmalade.
Me:� A marmalade stain?� Where?
Her
(impatiently): No.
Me: You
know that marmalade is a kind of jam made from oranges?
Her:
(Pause) But in the fountain Mummy, a marmalade.
Me:
(Peering into the fountain) Do you mean a mermaid sweetheart?
Her: YES.
