Invitation!

Disclaimer: I do not own Ninjago, Lego Movie, or the Lego Batman Movie, I only own myself and this story.

Whoa! You've been invited to an awesome sleep over! But it turns out, you've been invited to a sleepover in another dimension, and you live in the real world... and it also happens that your favorite Ninjago and Lego Movie characters were invited too! What happens? Will you have fun? And who invited you?
