VB: Veemon (outside DT), or Cybersramon in B2 (easiest way). Special plate egg.
ME: Pilevolcanomon in Western West (blue bordered rock egg), or a few other digis in B2 like Cyberdramon or Sinduramon (plate egg).
WG: most elusive one. DT Puppetmon chiefs drop them and maybe Gryphonmom in Infinity Ice (but I never got one from Gryphonmom so it may just be a rumour).
Edit: hmmm, just noticed the thread was 2 week-old. Feel free to ignore if it's no longer relevant.
