Here's My Short Review:
I thought this episode was pretty decent. It was kind of fun, it had a good but kind of odd plot. However Kenny was really ugly, it was kind of dull it various points in the ep, but I'll give it a:
SpongeBob's KTC fan club card has the same picture from when he "got" his license in Ditchin'. And the wash your fins poster from The Krusty Krab Training Video. S8/S9 have so many past ̶̶episode references that it's crazy.
That episode wasn't that funny, but was cool seeing another land creature in SB other than Sandy.
Well, not much to say about it, maybe they did this episode because of people obsessed with cats nowdays(that days aswell) :P
And that part where SB paints his face, is really creepy o.o
Actually people wondering how Kenny knew SpongeBob's name, let's remember that he uses a name tag when he's working, there's even a episode for this :V
I just don't know why they don't animate him with his full uniform.(name tag and hat)
This episode was pretty good. The plot was kinda good. I liked the character Kenny, because he is nice. Sandy was kinda jerkish here, and the ending was kinda stupid and dull. There were some funny jokes. 7.5/10
I haven't seen the whole thing (except the end), but...that ending was awful. When you almost die of asphyxiation, you don't walk it off and say "I GUESS THIS WAS A WAKE-UP CALL TO (slows down dialogue and turns to the screen to let the 3-year-olds hear you better) BE HONEST, ALL I GOT FROM THAT EXPERIENCE WAS A DUMB MORAL". Wasn't Kenny the least bit traumatized? And why would you keep looking up to a so-called "hero" after you find out he's a liar? And those last few lines about "being the cat that likes water"...That doesn't surprise/inspire anyone. Anyone can like water. No one's going to go "Oooh, he's the best thing ever just because he's a cat that likes water, oooh". It'll get a few scattered claps, but no standing ovation...
The concept is poor, too. Wasn't Mermaid Man supposed to be SpongeBob's hero, and not some deceitful land creature...?
I might be in the minority here, but I really enjoyed this episode. All the characters were likable and funny, at least to me. I loved Spongebob's obsession with Kenny; it reminded me of his obsession with Kevin in season 2.
