After reading a horror book, SpongeBob becomes nyctophobic. When at the Krusty Krab, Mr. Krabs suggests SpongeBob to buy a nightlight, so he will have comfort or convenience in dark. However, SpongeBob invests in as many nightlights as his pineapple house can fit, and even tags with Patrick for a sleepover that is guaranteed to keep the creatures of the dark away.
