You know, I can't be sure Gemini. The Tesco website has a description "includes Harry Potter Owl & Trolley LEGO Mini Toy" but no proper box picture whereas HMV have a box shot but no description.
Who says you can find anything on the net ??
The picture of the minitoy on the HMV version doesn't particularly look like an owl but it does look like a trolley so . . .
Ebay is no help in this regard either . . .just the usual bone-idle stock photos.
Something else to investigate . . .will report back when i have the answer.
