Lloyd adopts a tardigrade as a pet in spite of his parents warning that they never live for long. Regardless of his efforts to keep Nutbum alive, Lloyd finds it apparently dead the next day - thankfully, Cornea knows exactly what to do!

Lloyd tries to educate PB about the danger of spiders by luring one out with a decoy fly - his clumsy attempts attract a curious spider called Julie, who PB immediately wants to befriend. Can Lloyd accept that some spiders may not be all that bad?
