I do like Aaahh!!! Real Monsters, but I tend to find it very boring that all of focus goes to Ickis, Krumm and/or Oblina , while the other students almost never get to do anything, even getting their time to scare humans. Does anyone know what Horrifica's scare method is? An episode about Zabliner could give them a voice and a personality. Some of the episodes focusing on the main trio could just as easily focus on a different student.
Some other Nickelodeon shows like Rugrats and Spongebob have no issues giving important roles for any of the secondary or supporting characters, so Aaahh!!! Real Monsters could do the same.
