This will be obvious to everyone, but... What Growlie said. I'd really like to see more Squidward and Squilliam. I don't even really mind if the rivalry's still there, but it'd be neat to see an episode where they had to cooperate with each other somehow would be so awesome. The way they bounce of each other is just awesome, which is why I love writing stories about them so much.
On that note: I just write what I want to see, because I don't feel terribly confident the writers are ever going to do it. I'm secretly afraid they're dropping Squilliam - considering his cameo in 'Keep Bikini Bottom Beautiful' 'Back to the Past' was just that, a cameo. A speaking one, of course, but that's all.
What I do NOT want to see, is more of "I Heart Dancing", in that, I don't want to see Squilliam just being a temper-tantrum tyrant who goes around smacking people with gloves and shouting - UNLESS they'd do a sequel, regarding the show he mentioned that Squidward was going to be dancing in, I'd like to see that (but not with him stomping around shouting the entire time). I liked him better portrayed as the cheerful stuck up jerk - who had childish temper tantrums (throwing himself to the floor and bawling, like in 'House Fancy', that was funny). Note: I did like 'I heart Dancing', including his part in it, that's fine. I just wouldn't like him acting that way for an entire episode..
But, shameless plug time, if anyone wants to know what I'd like to see, check out my fanfics in Fan Creations. Those who haven't read "Lemonade" would probably like it, since I tried to write it in the mood of an episode and there isn't Squid/Squill shipping there, just friendship. (It's also the most liked one I've written and shared so far.)
(I'll link in a spoiler, so as not to totally abuse this thread.)

I like this idea too, honestly!
