When picking up, scoop around midsection. Avoid approaching straight at his head or trying to pick up at head area. Warm things coming towards his head are viewed as food or danger. As another poster said, be confident and quick. If you're slow and hesitant, that can also signal mouse. My corns have pretty much three thoughts: om nom?, om nom!, and oh it's her again lol. They think everything means food until they're somewhat rudely scooped up, then they're very curious and explore. Just support his body and let him cruise, and redirect rather than drag him back. Dragging back can lead to scale damage.
