Headscratchers / The X's

• So how can Glowface smell anything outside his globe anyway?

• What prompted the X's and Y's to arrive at Glowface's lair at the beginning of "Y's Up"? Considering all he was doing at the time was eating Glowy-O's, what the two families did doesn't make sense.
  • And speaking of "Y's Up", why does Glowface have a setting for himself on his Money Bestinkifier?

• What was the deal with the S.N.A.F.U. candy company that the X's destroyed at the beginning of "Wealth vs. Stealth"?

• How did Tuesday and Truman escape the trap they were in during "X Takes a Holiday"?
  • Earlier in the same episode, why do the parents consider leaving the kids with a sitter when Home Base could keep an eye on them just as easily?

• In "Live and Let Diaper", why does the baby the X's look after take a liking to Glowface?

• Why are the scores for the first four frames of the "X's vs. S.N.A.F.U." bowling match different when the final results are shown near the end of "Pinheads" than they were over a minute before then?
