Yep.
To an extent.
Seriously, who the hell drew that?
Someone who knows a lot about a perfect world.
The flying sled through the night represents the kid symbol of Santa Claus. Santa represents GIVING. The rainbow trailing behind the sled represents HAPPINESS. Riddler riding the sled of GIVING and HAPPINESS represents PEACE. The pajamas represent that appearance does not matter, but it's who is on the INSIDE that matters.
