Baldi was hired at Here School for teaching kids math. Eventually he received a package with makeup in it. He never tried makeup on so he tried on the lipstick. But the package was from Playtime as a prank. The lipstick was coated with permanent marker so it wont come off.
Baldi: MAAAAA WHY IS MY MOUTH RED IT SHOULD HAVE COME OFF BY NOW
Playtime: LOL Baldi you fell for my prank now you have red lips
Baldi: PLAYTIME MAAAAA
