Professor Willow dialogue
First part: Oh, Trainer! You've dropped by just in time. As I was out on my regular walk one evening, I stumbled upon this odd stone. Something told me to bring it back to my lab for further research, and ever since then, strange things have been happening. Papers shifting around, water glasses tipping all by themselves... When I tried using my computer to research it, I got an error message with the number 108 flashing! Trainer, can you help gather some data on nearby Ghost-type Pokémon? I have to believe we can solve these spooky occurrences with science! Second part: Trainer, thanks so much for your help. I did some research on Ghost-type Pokémon, and I think there's a Ghost- and Dark-type Pokémon that is bound to a strange stone. I can't say for sure just yet but it seems this Pokémon may actually be composed of 108 spirits bound together. So maybe if we catch 108 Pokémon, it will appear? Good luck, Trainer! And...would you keep the light on in the lab for me? All this spooky research is making my hair stand on end. Third part: Wow, Trainer! It seems we've had a spooky brush with Spiritomb! I can't tell if it's the weather, but I've got the shivers! You know, I feel confident that we can solve anything together, Trainer, even when things get scary. I'll be in touch soon!

Trivia

 * The number 108 is referenced throughout the research, because Spiritomb is closely linked with that number - Spiritomb is formed by 108 souls trapped inside a stone, and that number is referenced multiple times in the video games, such as Spiritomb being #108 in the Sinnoh Dex, its defense and special defense being 108, a Spirtomb being able to be encountered on Route 108 in Omega Ruby and Alpha Sapphire and its weight being 108 kg.
