What Is Up With Dora?!?

Is anyone other than me thrown off by the size of Dora's head? What is up with that thing? She looks like a textbook case of hydrocephalus. God bless her mother on the day of her birth.

Here is a count of things that Dora's head was larger than in the episode that I watched with Banana last night:

1. Her parents' torsos and their heads put together

2. A boulder

3. Half of an alligator

4. A window

5. A baby leopard

Surely this can't be good.
