True stories from my house:
1.) My kid wrapped the snake around his belly while reading on a wicker wing chair... he tried to get up but half the snake was coiled around the wicker behind the foam back. He got "stuck" to the chair. It took us a loooong time to unravel the snake out of the wicker diamonds.
2.) Another kid put the snake on a microfiber armchair. The snake was able to wedge himself through the crack between the seat and the back. She then happily crawled inside the arm of the chair and stayed there. We had to break apart the chair to get her out... and that's after she pooped and peed in the foam.
3.) My kids play fort with my snakes. They would put a snake under a "fort" with a flag and they would draw battle lines and have their toy soldiers/tanks/airplanes/whatever fight on the "battlefield", etc. The snakes don't go outside of their fort-hides. They never do.
4.) My pastel escaped once. We found her coiled inside a drawer about 5 feet from her enclosure.
5.) The albino escaped once too. We found her under the sink cabinet (behind the kickboard) not more than 10 feet from her enclosure.
6.) Our western hognose escaped once. W found him happily crossing through the middle of our bedroom floor... completely on the other side of the house from his enclosure. I have a 3,000 sq foot house.
So yeah, my ball pythons aren't really the most fun of snakes although they are still really cool to handle. They don't go places. If they're cruising - it's because they're trying to find some place to hide. Once they got their safe spot, they're staying there until they get cold or get hungry.
My western hognose, though... yeah, he likes to cruise around and pretend he's a cobra or something.
