You would think, wouldn't you, that after all the havoc Zoonie has wreaked in the Space City Tower, that he would be forbidden to set foot in it again. And didn't Commander Zero even bother to mention to Venus what had happened? I was wondering why the heck Zero gave Zoonie a whistle in jail, and walked off chortling to himself, until I saw Zoonie on XL5.

Venus seems to be doing her best to live up to the stereotype of the classic dumb blonde. She tells Steve about a gas cylinder which, if released into the air, would kill all of them in a matter of hours. She then places it precariously on an open shelf in her lab. If XL5 had needed to make a sudden acceleration, deceleration, or sharp turn, that thing would have gone flying. After Zoonie startled her with his whistle (and lucky she wasn't carrying something hazardous in that glass dish) she took the whistle and put it right next to the gas cylinder.

Venus does know her lazoon, however. Hearing evidence that Zoonie has retrieved his whistle, she knows that he must have knocked down the gas cylinder, and she knows that it must have opened up!

Lt. 90 sure gets around. After overseeing the return of XL5, he leaves the tower, rushes over to another building, and tends to the decontamination of the crew. I would have thought that a doctor, or at least a medical technician, would be in charge of that.

The Floran people are slow as well as suspicious. If Steve and Co. had really intended death and destruction with the bomb they set off, would they then come down into the atmosphere?

I notice that the WSP uses the word "human" as a general term for "sentient species". When they were concerned about the effects of the bomb, Venus or Matt explained that it would only affect plant life, not humans. The Floran people are not humans. "People" or "Animal life" would have been better terms.

I can see why Floran is generally considered a lush planet, given how fast the plants grow. How do they keep them from overrunning everything?

Those man-eating plants would be handy guards to have around one's castle.

They showed the crew waiting in the tower for the thick, heavy plant to reach the window, but then showed them coming down using a thin, fragile-looking vine. (BTW, it was very gallant of Steve to have Venus go first. If the plant turned out to be not strong enough to carry their weight, he wouldn't be the one to go crashing to the ground!)

Venus had stated flatly that if the gas got into the atmosphere, they would all be dead. In Zoonie's case, all they had to do was turn on the fans. They could have at least shown Venus giving him some sort of antidote. Then again, they should have shown Venus putting on a gas mask before rushing in where poison gas was still swirling about. She's dumb blonding again!

I can see where they would want to get back at Commander Zero for the whistle, but is it really a good idea to antagonize your commanding officer?

BTW, it didn't occur to Steve that he was also tormenting Lt. 90, who had nothing to do with the whistle ploy. That guy never gets any breaks....
