Oda and Tilda fit together like two pieces of Lego: perfectly! Oda is quick as a flash in most things (except for tidying up) but, unfortunately, she often fails to notice important details. Tilda is just as slow as her pet snail Miss Marple, but she usually never fails to notice even the tiniest detail.
When Dracula, the shaggy dog from the third floor, disappears, the two are absolutely certain: This has to be a genuine case of dognapping! They have to save Dracula! After all, they could earn the offered finder’s fee of 250 euros – that is enough to buy 500 small bags of sweets at the kiosk! But then a lot of things get in their way and, suddenly, the two Lego pieces do not really fit anymore.
