I really enjoyed both of the episodes.
I loved "Are You Happy Now?" even though there was no need for that because Squidward has had many happiest moments but he can't remember obvioiusly. So yeah, even though this episode didn't need to be made, I really loved it and it was funny and original all the way through.
I really liked "Planet of the Jellyfish", it was actually better than I expected but it didn't look like it would be that good of an episode but I was WRONG. In my opinon at least, it was awesome and pretty funny. The ending was predictable but oh well
Are You Happy Now?: 10/10
Planet of the Jellyfish: 9.5/10
