This episode was centered around the boys.It all started out when Mr. Garrison's class went to a school trip to a plantinium. The owner greets the kids with joy and invites them inside the plantinium. Once inside, the kids sit on a chair while the owner brings in pretty colors from outer space. After that time, the boys test it on Kenny, giving him a seizure and die. The boys try to alert the South Park folks to end the plantinium's madness. Meanwhile, Cartman auditions for the Cheesy Poff commercial. He is accepted and got the role.
This episode was amazing plotwise. I think the plot was the good for thisd episode.
Its sub-plot centering Cartman was a nce add to give you further to watch.
The humor is its downside. It had many memorable scenes and jokes. But I just think it lacked humor.
This is better then many other Season 2 South Park episodes. I recommend this episode for old fashioned South Park watchers.
