VERY CLEARLY a pilot, but it's easy to tell and see how this pilot becomes a good foundation for the show this eventually becomes. The animation is rough, but given that this is a pilot and the character designs being as amazing as they are, it's easy to overlook and just absorbed into the world. This very first episode is actually surprisingly funny (my favorite part being when finn (i guess it's penn in this first episode) tries to tell a joke to lady rainicorn (which in this is Princess Bubblegums Rainicorn) and all of Finn's attempts completely crash and burn due because Lady Rainicorn can't stop crying ugly style) it's just so charming and clear why Cartoon Network picked up the series when Nickelodeon declined.
