Bowser has only one son?

Ugh, I watched the rest of the boss battles I hadn't seen yet and they get progressively worse. I thought it was cool that Wendy called the fish in to be more difficult, but then you see stuff like Morton and it's just sad.

I do like the Wii U bosses they showed so far. At least they are given even more individual styles to the bosses, and so far none even had magic wands.
