lol, I'm glad I'm inspiration
The only thing I have to say is I don't think Digimon is that random. Apart from Agumon evolving to Garurumon or whatever, most clear cut digi lines such as Augmon stick to a reptilian orange creature with each stage of evolution gradually getting more and more armor.
Usually elements of Digimaking revolve around more than just "He must have a piece of armor" or "he must be wearing boots."
Now that doesn't mean you couldn't have a kangaroo or Froggie themed Digimon, but it's really random to be jumping from a metal ball, to a dinosaur head, to a frog, to a kangaroo, to a bestial creature, and then to a human. It's usually something that sticks to it's family group (with the exception of Digimon randomly evolving into other types of Digimon, which isn't even 'allowed' in DWC)
I'm not bashing your tutorial, but this point can cause some confusion
