Spinoff/Mobile most memorable/fun spinoff moments!

the title explains it all, really. c: i'm sure most of us have played some spinoffs, so let's talk about them! what are some memorable moments you've had while playing them?

Definitely has to be besting Mt. Battle with nothing but my Umbreon/Espeon starter duo in Colosseum (AND in one sitting I will add). I'm not sure how it even really happened, just that the Pokémon combinations and levels meant I was somehow maintaining a good levelling curve whilst not really have any immediate dangers thrown my way.

Something I've also not been able to properly replicate since!

Your partner Pokemon telling you they're Mew and twisting the player character having to go back to their own world will never not be something that sticks with me forever.

Also, finding secret bazaars and treasure rooms in PMD Sky that was amazing, and fun.

Also abusing the wonder mail generator system to get items you can't normally get.
