In Double Take, when "At the end, she looked at the camera, wondering if the audience knew what exactly happened." the "she" is Matilda, breaking the 4th wall.
See what i mean??
Red also breaks the 4th wall. Here's my proof:
1 second after that, Red looks at at the camera.
I saw these, they break the 4th wall often.
Theres more characters who do this including all of Stella's flock and
King Pig does this on Tooth Royal:
but the show that always break the 4th wall is the loud house
(they should stop breaking the replacements of the 4th wall)
What do you think?
