"It was a day like any other..." it's what I would say if it wasn't because it's your birthday! And your dear friends had no idea! :D

If it wasn't for April, the 4 of them would've been absolutely oblivious of this special day. With the little time they had of preparation, Mikey "made" a cake, Donnie went outside with April to look for a proper gift, Raph, Leo and Karai worked on decorating the lair and Casey found out like half an hour after they all started preparing to celebrate and he went to look for Donnie and April to "help" them look for a present.

2 hours later. (Now) you enter the lair, it was quiet, and by now, you know silence around these four is dangerous. You immediately start to look for them before suddenly

"¡Surprise!" Everyone exclaimed as they left their hiding spots, Mikey entered the living room with the most non-edible cake God had let be made.
