Chyanna Richards, who lives in the home, told KTRK-TV, Houston, she doesn't know if it's mold or mildew in the bathroom but said the appearance of Jesus' image has meaning.
"Maybe it means something. Maybe look into yourself and see if you need to change something in your life," she said.
The mold began growing in the bathroom at the Splendora home a couple months ago when Thomas George, who lives in the home, was in prison.
"He's just watching over us to make sure nothing wrong happens or I get in trouble and go back," George said. "It gives me inspiration just to do better."
Neighbor Michael Bearden said he believes the image is of Jesus but joked it reminded him of someone else as well.
"Jesus. But it kinda looks like me!" he said.
