Ella is about to help Mr. Jackson with the party decoration box, which mysteriously has a hole in it, when Henry, Lisa and Lottie excitedly call out to Ella as they think they have seen a strange creature in the garden. Lisa thinks it’s a pixie, Lottie thinks it’s a goblin and Henry thinks it’s a space alien. The four of them lie in wait for the strange creature to appear, enticing it with all kinds of goodies, from food and toys to sparkly things. Finally the strange creature does make an appearance. But, it’s neither a pixie, a goblin nor a space alien. It is Joseph the mouse all dressed up in tinsel and decorations from Mr. Jackson’s box!
