This is yet another episode of the horribly animated "Star Trek" cartoon series. While the 1960s and 70s were a terrible time for animation, the horrid quality of this show sets it apart--being even crappier than the stuff coming from Hanna-Barbera! With slide show- like animation, it's hard to imagine much worse!
When the show begins, somehow the Enterprise locates Carter Winston- -a famous explorer who's been lost for several years. However, soon it becomes apparent that it's NOT Winston--it's something more akin to Squiddly Diddly! But this squid-like being can assume all sorts of forms--human and non-human as well as non-living! But when the creature takes them into the Neutral Zone and the Romulans show up, the crew is forced to deal with TWO menaces at the same time.
This is a fair episode but suffers not just from the craptastic animation but the female guest character who is an idiot. I assume if the show had been made today, in addition to better animation it would also feature a female character who isn't dumber than a zucchini.
