Christmas. The time of year the holiday special toons were free from the basement. But..it was nearing January. Meaning they had to be locked up and hidden from the public again for the remainder of the year. And..someone broke the news to Rudie. (Which is not usually the plan, as that toons entire personality is being silly and revolving around Christmas.)
to put it shortly, Ruide broke down. After being told repeatedly that he was going to be hidden for the year again along with his friends just made him..loose it.
the other toons decided to task you with finding and comforting him..as you were one of his close friends.
you found him on one of the Christmas special floors, crying in one of the dead ends of the place. Fidgeting with a bright red ornament
“No..no no no! Christmas can be over no! It’s can’t it can’t it can’t!..please no..it- it’s always Christmas! Yes! Always!…haha..hah..sniffle”
he broke down sobbing again
