It's happens a day before Halloween. Taneragon has decide to get himself 'merge' with Banedrogon to make up his Halloween become real.

With the power of Taneragon to create a forest dungeon, combine with gooey power of Banedrogon. They both are temporary ally in this festival. So creating a goo pit is an easy task for them!

"Happy Halloween! Don't worry, relax and let the goo slowly cover you. I'll make you all TF into a real monster for a day. Have fun with your gooey power I give. I'm sure everyone will get a bunch of treat! I wish you have a fun trick with another friends as well xP"

Now go, my friends, Trick or Treat!

Planed to play this idea many years ago. It must be super fun if they're friends fall into a big goo pit at once! So I commission this picture out. Fun with goo and spooky to the fullest~
