Nebby, the cute little cosmic cloud that everyone thinks is adorable (you better). BUT. We know about the memes. You are a bad little Psychic Type that never stays in the bag. List your frustrations of Nebby's bag escaping skills. If you were Lillie, what would you do to keep it in the bag? ... I wouldn't even have a bag. Because I would be a certified trainer and shove that little dust cloud into a Pokéball!
HA HA HA HA HA!!! ~The Story Of A Glitch-Obsessed Trainer And The Dust Cloud Who Wouldn't Stay In The Damn Bag~ The Trainer first tried non-conventional methods, like 'accidentally' forgetting the cloud at a Center because she was annoyed with it. Then, the Trainer took lots of pictures of the cloud and posted them on the Internet as unfunny memes Finally, the cloud drove the Trainer crazy and the cloud was left at Hau's house permanently as the Trainer went on the GTS to find a different Solgaleo. #MissingNo
If I were Lillie and couldn't use pokeballs...I'd zip up the bag and stick a padlock at the end of it. Unless Nebby now has the ability to phase through bags
I'd also use a Poké Ball. Then I'd evolve it into its final form so it can defend itself and look awesome while doing so.
Lure it into Kurumi's bag with some Pokepuffs, and then slam it shut. Let's see Nebby's little smiley face go down!
I just remembered why Nebby is an escape artist though. The only two moves it has is Splash and Teleport XP
Dang it The little cloud will escape every time then... unless there's another item that nullifies Teleport.
