"Okay, I retrieved the box from Themyscira!" Wonder Woman said as she got back to the Watch Tower.

"Where is it?" asked Batman.

"Oh, it had Queen Bee in it, so I took her to jail." Wonder Woman said.

"Where's the next box?" asked Miss Martian.

Wonder Woman held up a tape.

"Play it." Wonder Woman handed it to Batman.

Robin popped up on the screen.

"HEY THERE!!! If you are seeing this, then that means that you found all the boxes!

Except one.

SOOOOOOO!!"

Robin cleared his throat and pulled out a piece of paper.

"You shall find the last piece of the puzzle in the place where it all began.

Where the Robin first appeared.

Find me and smile.

For you completed the puzzle!"

The video stopped.

"Where Robin first appeared?" asked Flash.

"Gotham City." Batman said.
