Okay, now that I finally got a chance to watch this episode, here's my review.
I thought this episode was somewhat weakly written. It could've been done differently and more efficiently and instead just felt like a one long joke stretched out over 22 minutes with too many rather useless filler scenes. The general story is famous zoologist lady pays a visit to the pet shop, freaks out when she sees Penny Ling and it turns out she's afraid of both gorillas and pandas. Blythe discovers the reason why and helps Tess McSavage overcome her fears. A rather boring-sounding plot but it could've been helped if the events throughout the episode were laid out differently and if there were less useless scenes. The Wizard of Oz reference was a nice touch, but not too special.
I think this episode could've been done without involving gorillas at all, and although the pets do get plenty of screentime, the scenes with the guest character, a female gorilla named Sunshine Sweetness, kinda take away a little too much time from them. This episode would've been better handled if it was about Tess overcoming her fear of pandas only and if there were a different guest pet in a different kind of subplot.
Speaking of subplots, I also notice how this episode seems to lack one; the characters just simply split up and converge at different points throughout the episode. While I don't consider subplots to be essential for an LPS episode, this one probably could've used one because it felt kind of long and drawn-out for me. I would rather have two short, yet fully-formed plots than one stretched-out plot.
I thought Mrs. Twombly was crazy but wow, this Tess lady was just downright insane... I'm surprised a woman like her could even be famous. She came off to me as pretty creepy.
I did not like the ending scene at all... This episode could've really used a totally different epilogue. Instead we get Penny Ling explaining why she was brave enough to hug Sunshine, which I thought was weird enough; I know Penny Ling is sentimental but to just hug a random gorilla was weird even for her. But what really struck me was her saying something along the lines of "I just did what Sunil and Vinnie do...and then I did the opposite!" ...........Um...what? Sunil and Vinnie were right to be confused about that and why the hell were the other pets laughing? I'm sorry but that was a terrible way to end an episode...
I don't usually do this, but if I had to give this episode a score, I'd give it a 5/10. I don't consider it a bad episode, hell, I don't consider any LPS episode to be bad, but they could've done better with this one.
