Then again Mikey still says he's 15 years old to Napoleon Bonafrog in the Northampton arc afterward...but considering it's Mikey maybe he was too dumb to realize he aged a year. 
I'm not sure if 5 years passed in-universe like in real life, but it was probably at least 3 years. |
Well, Mikey is confirmed to be an immature idiot, so that's why after every season, I always assume that they're a year older than before.
