In almost the exact middle of that two-hour special, Shinichi's mother is driving him to the reading of her friend's father's will, hoping for him to solve a mystery there for her. While riding on her motorcycle she is wearing a jumpsuit, which is partly unzipped. The reason? She is ferrying Shinichi (or Conan, in this case) in her cleavage, which is surprisingly pronounced, as well as accompanied with shocking breast physics.
Now, before anyone gets their hopes up, know that this is about the only bit of obvious fanservice this series has. All the other fanservice is so subtle you won't likely notice it if you're paying attention to each episode's plot.
I was so used to not having fanservice in Detective Conan that I was positively shocked at this display of boobage and physics... O_o
