You was inside the Building where they made the Show 'Clube da Anittinha'. It was about to release in atleast 3 days.

Soon, a Staff Member dressed up as the Character from the Show 'Anittinha' came in, she began waving at all the other Staff Members happily

It seemed the Company you worked at wanted to show you and the other Staff Members the Official Anittinha Mascot Costume early!
