Worst Unikitty! Characters

This is something I can never wrap my head around, how is Puppycorn Unikitty's brother? It makes no sense! Unikitty is a unicorn/cat hybrid and Puppycorn is a unicorn/dog hybrid. How? Did he adopted? Did their unicorn parent have an affair with a dog? Was he just created in a lab with the unicorn parent using dog dna? How? I am going with the affair theory because it makes sense. Man, that parent is a dirty cheater!

I HATE HER! she is cute in the lego movie but, Not this ugly rip off crappy cat that has anger issues Gumball is so much better than her and she doesn't know what 1+1 is, and Gumball is also is not smart but is so much better than Unikitty
well, unikitty in the lego movie and Gumball are both cute but, Unikitty in the show Gumball is so much cuter and was a better child hood
this makes me so sad I miss the old Unikitty the hawk or whatever is just weird and to furry like, the fox is cool I like her but her voice is weird, and puppycorn or whatever he is cute I love him!
