Uncle Poodle and Pumpkin Fight it Out Over Child Molester

Mama June's daughter is staying firm with her mom, and attacking Uncle Poodle ... claiming he doesn't care about their family ... all he's trying to do is make a buck.

14-year-old Pumpkin went wild last night ... posting on Instagram a rant that Poodle is spreading false stories about her family ... specifically June's relationship with convicted child molester Mark McDaniel.

But Poodle fired right back ... saying, "The girls will be just fine. They are upset now and will understand the gravity of the situation. All I can do is love them unconditionally regardless of how they currently feel."

It appears June and the kids are upset TLC cancelled "Here Comes Honey Boo Boo" after TMZ broke the story ... but Poodle is saying the show isn't as important as the welfare of the children.
