Digimon Adventure (PSP, English Sub): Part 11: Side Quest 4
Right after this Toy Town episode starring Mimi & Palmon, you get a Sub Episode that brings you back into there.
And this is probably the most minimum-effort episode of anything in the entire game. No walking. No battles. It's just a questionnaire.
----------
Mimi & Palmon return to the dusty plains that contains all of the vending machines. Mimi still hadn't gotten her cola beyond the Monzaemon incident, and she was ready to finally fix that.
Of course, her vending machine shat out yet another Numemon that wanted to date her. Mimi was really getting sick of this at this point.
But this Numemon came prepared. She presented Mimi with a can of chilled cola! The catch is... he'll give it to her if she dates him.
Palmon overestimates her human partner's ability to refuse, because Mimi decided to go for it if it meant she can finally have her favorite drink.
So off to Toy Town they went for their unholy date... much to Mimi's digust...
----------
Again, this is just a Love Questionnaire. No fights to worry about. You don't even get to control Mimi.
Just answer Numemon's three questions, and then he'll go through a summary of what you got correct at the end. If you got them all correct, you get an extra item.
----------
Nonetheless, when the date is completed, Numemon finally gives Mimi her much-desired chilled cola!
But from there was bad news from Izzy's inspection of the drink...
The cola was very long expired. It was too syrupy and disgusting to drink. Not a problem for a Numemon, but for anyone else, though...
So then... that date Mimi forced herself into... It was all for nothing...
