Why did Frog get mad when Bo drew the picture of the elephant on the net

Because he was more worried about getting the elephant back to Texas and getting the money, than he was Charlotte's health and well-being.

It would've put too much pressure on the elephant's stomach and possibly caused complications or early delivery. He wanted to lift Charlotte off of her feet. It'd be like a pregnant woman laying on her stomach on a sling and lifting her feet into the air.

As I said: think of a pregnant woman, who's almost full-term, being held in the air by nothing but a sling around her stomach/abdomen. Her feet aren't touching the ground and she's not holding onto anything. The ONLY thing holding her is a net across her abdomen, while her arms are hanging over one side and legs are hanging on the other side.

When I was pregnant, as I've also heard from plenty of other women, I could barely wear a seat beat because it pushed on my abdomen and caused excruciating pain from 7 months on.

Don't take this the wrong way, but it's something men really wouldn't understand.

Nice, yeah, but his head was in the wrong place. He was too focused on completing the mission and missed what was really important.

She didn't like the way the drawing looked
