1 Parappa yanks his hat off and reveals Finn's glorious golden hair from Adventure Time hiding beneath it, and the sheer spectacle of it causes Lammy to break down crying and finally admit "her" actual gender to everyone in the general vicinity
Why, you may ask? A certain feeling called hair-length envy
How, you may ask? By stripping "herself" naked and revealing that "her" chest is actually covered in hilariously exaggerated muscles that make it look as if "she" has man-bewbs
Which, of course, would make hardly anyone in the general vicinity surprised, for numerous reasons that start with "horns" and continue with "canonically embarrassingly flat and featureless chest"
2 Obligatory crossover with HiHi Puffy AmiYumi and Gitaroo Man
This could work with Parappa too, honestly (not just Lammy)
3 Lammy and Katy get married to each other and have adorable sheep-kitten babies together
Yes; believe it or not, this IS actually canon
4 Hairdresser Octopus cosplays as Toko Fukawa from Danganronpa
5 Parappa has an Epic Rap Battle Of History with Eminem
6 Guru Ant, Prince Fleaswallow and Lammy (all dressed up as the most deliberately stereotypical 1960s hippies possible) engage in a weed-smoking contest
7 Chop Chop Master Onion grows fifty feet tall and fights Paper Godzilla
You know, like in Playstation All Stars Battle Royale
8 Lammy literally plays Katy's and Parappa's bodies (preferably their naked bodies, in fact) like guitars
Also appeared in a Tumblr comic at one point
9 Captain Fussenpepper drunkenly flies an X-Wing into the Death Star while absentmindedly rambling about how the military was "back in his day"
We very seriously NEED more video game levels with the original Fright Flight's degree of memorability that take place in airplanes
10 Lammy looks herself up on Paheal.net AKA Rule34.com (and all of the furry sites as well) and is found curled up in a ball and shivering in traumatized fear in the corner of her bedroom by Parappa and Katy shortly thereafter
Prostitution, objectification, it's all in the art
