Psychonauts 2 has a number of side quests to complete, with Lili being one of the first characters to offer a side quest. Lili is one of the returning cast members from the first game and stands alongside Raz during much of his journey.
Lili's story picks up from where it left off in The Rhombus of Ruin, touching upon Raz and Lili's feelings for one another and that one time they kissed. So in order to stay in Lili's good books, you are going to want to complete her side quest.
Lili's quest becomes available at the start of Act 2, once The Psychonauts return from Lady Luctopus' casino and you gain access to The Quarry. She can be found attending to her garden and taking some time away from the busy life and hectic nature of the Psychonauts organisation. From here, she'll ask you to find her a super rare fungus, which can be pretty tricky to find.
