Boxal and Pix are siblings, also Boxal and Pix are cousins with Boxten.

Boxal and Pix have full names, those being Boxalton Birch Citrust and Pixelite Oatmeel Citrust respectively, just like how Shelly, Astro, Sprout, Vee, Connie and Dandy have full names too (as seen on the Dandy's World wiki)

Twisted Pix hates Twisted Boxal and Boxal

Twisted Boxal is good friends with Twisted Shelly

Boxal really likes to focus on tasks at hand

Boxal and Gigi are rivals, and so are the Twisted counterparts for that matter.

Boxal and Twisted Boxal hate Delilah because of what Delilah wrote (it's in the Workshop floor)

Boxal can feel objects in his containment spot on his head, Pix can feel it too, rustling about her sweets in her container, speaking of the sweets in her container, they are all the Candy type items in the game, and if they were all removed from her head, she would die.

Boxal acts like what I think a Toon Handler would act like to Toons, but instead it is strictly for Boxten and Pix only

Boxal can be shook by change, he is also autistic and so far is the only Toon with Autism (as of this post)

Boxal is a cat person while Pix is a dog person

Boxal and Pix unlike many other OCs have no canon romance stuff like the official D.W cast

if you forcibly make Boxal or Pix's heads open, it will cause a bad head injury, please don't do it to them.

and that is all, have pizza for reading all that :)

(this was the best GIF I could find of Pizza.)
