Honey Boo Boo will have a safe, stable home free of all convicted child molesters ... so vows Uncle Poodle, who says he'll file for custody if things get bad at Mama June's.
Sources connected with the family tell TMZ ... Uncle Poodle and his fiance Alan have researched the ground rules for winning temporary custody. They say they have the financial wherewithal to support Honey Boo Boo, and they're getting a new, larger apartment with a spare bedroom.
Our sources say ... Poodle and Alan are ready to file for temporary custody if June does not completely sever her relationship with Mark McDaniel. They will not ask for permanent custody because they'd like to see Sugar Bear eventually care for Honey Boo Boo ... when he gets back on his feet financially.
They are talking trash about S.B. ... calling him "an idiot" for hanging out with June.
As for 14-year-old Pumpkin ... they have no desire to get custody of her -- she hates them.
