The Theme (It's Party Time) Puns

It was my son's birthday, and we were doing a Thomas the Tank Engine theme. Went to the party supplies shop, and one of the things we got for the party was a helium balloon with Thomas on it. Gave it to him, told him to hold on to it, otherwise it would float up into the sky, all the way to the moon as Peppa Pig phrases it.

Anyway, I'm looking around and I notice something weird... there are Transformers helium balloons, Peppa Pig helium balloons, Barbie helium balloons, Thomas of course, various superheroes... but I notice the complete absence of Elsa and Anna on these balloons. But Frozen must be the most popular theme ever for girl's birthday parties, I would have thought. So why no Frozen helium balloons?

I asked at the counter, and they told me that they used to have them, but they got too many complaints. Apparently every time a parent gave the balloon to a kid, she'd just let it go...

Okay, this is my first time posting to this sub. :) I work at a kid's play center, and with the big Frozen craze going on lately, we have about five Frozen themed birthday parties a day.

We had a Frozen birthday party a few days ago where someone brought in their own balloons, and one of which has Elsa on one side of the balloon with Anna on the other side. We have a new girl that I was training at work, and she pointed out the balloon today and asked, "Wow, how did that get there?"

With the biggest grin on my face, I proudly said, "I guess someone just accidentally... Let it go."
