Wicked Science: Spiderboy. Garth's obnoxious little cousin Rodney is in town, and when he starts causing chaos at school Garth pulls him into Elizabeth's lab to try and keep him out of trouble, only for the little idiot to start messing around with Elizabeth's "genetically enhanced" spiders... This is another really fun "monster movie" episode, with some great jumps and big laughs. Another really good episode, only 3 left now (including the 2-part finale), which I'm rather sad about. I've really enjoyed revisiting this show, with season 2 in particular being gold.
