Despite the art style still not being where it would later end up, and the characters still being in their early stages, it’s a great episode. We learn so much about the Plaza and are introduced to (and see again) some great plazoids.
Who said you need a proper villain to have a good episode. All you need is a teenager with attitude, some magma/lava, and a mathematically perfect haircut.
And a jar of pickles. Open it once or twice at your discretion.
