Mario, Luigi and Skippity as the Ghost

They are at it again! I surrender- throw my hands up! I realize we are not parenting experts but our two kids are intelligent and I thought we were doing a fairly good job. What they recently did has me a little skeptical about their futures and whether or not they will be ready to be on their own in about ten years.
Halloween is around the corner. I took them to Party City to get their costumes. I really thought our oldest is too old and too tall to still be dressing up. She's tall for a fifth grader but still a kid. So it was fairly easy to get costumes. They wanted Mario and Luigi costumes!
"Let me get an eight for him (pointing to our eight-year-old son) and a...um... (sizing our daughter up) what's the largest size you have for kids?" I asked the store associate.
"A fourteen!" he answered. "But she's kinda tall and we do have these costumes in the bigger (adult) sizes," he informed me.
I scanned the bigger size wall. Then went back to the kids' wall.
The fourteen was $19.99 and the bigger ones were $29.99.
Yes I know it was just a ten dollar difference but hey I could use that difference to get me two white chocolate mochas from Starbucks later in the week!
They tried them on and yes her one-piece was a little short and the crotch looked to be pulling but hey she could put on some blue socks to match it and call it a day. She wasn't complaining. Too busy practicing her Italian accent in the mirror with the mustache upside down.
The associate's eyes went directly to the bottom of the pants. "We could-"
"We'll take that one," I interrupted.
Unless he was going to add cloth to it or offer buy one get one free... his opinion was not gonna be needed anymore.
So they were elated! So elated that they tore into the costumes in the car on the way home. The giggling in the back seat with the attempted Italian accents made me turn the volume up on the radio.
"Hey! If you play with those mustaches and they don't stick on Halloween, I guess you will be using scotch tape, glue sticks or a black marker!" I warned them.
Well they weren't content with the two of them having costumes... they decided to make a ghost costume for Skippity.
I didn't know about it until I heard our son yell.
"She bit me!"
"Who bit you?" I asked as I ran to investigate.
His sister made the ghost costume and convinced her brother to put it on Skippity. And they thought it was okay.
Skippity is one of our two, red-eared slider turtles. And Skippity is feisty!
I could just see the little bubble above Skippity's head:
"Don't you realize I am a dag-blamed turtle?"
