Found important lore on tiktok of all places
OWCA deadass said “yo Heinz we’re sending a platypus to kick your ass. his name is Perry xoxo”
I always assumed that it happened like this:
Perry: (crashes through window)
Doofenshmirz: A platypus?!
Perry: (puts on hat)
Doofenshmirz: A—platypus wearing a fedora?!
(Perry hands Doofenshmirtz a business card. Doofenshmirtz puts on his reading glasses.)
Doofenshmirz: (gasps) PERRY the Platypus!
I hate how in-character this is
