Headscratchers / Jack-Jack Attack

• Why doesn't Jack-Jack set off the sprinkler system? The self-destructing message set it off, but a flaming baby doesn't? What?
  • The may have left it off after the message incident, especially depending on what excuse Bob came up with.
  • Sprinkler systems get triggered by smoke. Smoke happens because the fuel is being consumed. No fuel, no smoke. He's just giving off heat and light, not burning away his body.
• At the end, the entire house is a mess, with the carpet singed, toys and junk everywhere and furniture destroyed. Then when you see Syndrome about to kidnap Jack-Jack at the end, the entire house is clean. Did he clean the house, replace the carpet and replace the furniture for them? What a guy!
  • Probably another of Jack-Jack's multitude of powers. Babies value familiar environments, such as their home, and would find it distressing to see it damaged/disordered.
• It is revealed that Syndrome showed up to the Incredibles' house to steal Jack-Jack. So it looks as if it is noon when he arrives and it looks like the sun is going down when the Incredibles get home. So what was Syndrome doing with Jack-Jack for all that time? When they arrive Syndrome has put Jack-Jack to sleep, so it implies that he was good at looking after him.
