There are a lot of bronies who joined in 2013
Some of them had fell for something I like to call the Magical Mystery Trap.
The Magical Mystery Trap is what I call bronies who thought MMC was the final episode overall.
This would usually occur if someone joins the fandom after MMC aired (Feb 16, 2013) and before S4 premiered (Nov 23, 2013)
Did you fall for the Magical Mystery Trap?
