Lego 21308 is one of my very favourite sets. When it was released, I was a little young for Adventure Time. But, when I started watching the show, I yearned for this now retired set. I finally convinced my parents to let me get it off of Ebay.

Pros:

Makes for an amazing setup

Very fun to build (especially while watching the last few episodes of the show)

Generous extra pieces

Good quality box

Printed faces

Good blocky yet realistic features

Cons:

Needs more characters (including the best character, LSP)

Grey parts on arms

Legs do not move

Box makes some characters look bigger than they are

They could have made a whole line of these sets...

This is a set that every major Adventure Time fan needs.
