SpongeBob's alarm clock, also known as Alarmy, is a 740 Foghorn Wake-em-Up Grand alarm clock in SpongeBob SquarePants' bedroom. It appears in various episodes, starting with the pilot episode "Help Wanted," and it plays its biggest role in the episode "Broken Alarm."
It going off has become a commonly used sound effect throughout the series.
It appears to be a repurposed, white foghorn and is kept on top of a barrel next to SpongeBob's bed. It has a light gray corner around its circular opening. It also has a red clock on the bottom of it that has a transparent blue glass screen. There is a switch behind the said clock to set the time.
In some of its appearances, it is depicted with a red snooze button.
Role in series
The alarm clock makes numerous appearances throughout the series and is typically heard going off near the start of an episode when SpongeBob wakes up in the morning. It typically blows air near SpongeBob's direction while going off and has transported him to his various destinations after he wakes up, as seen in "Something Smells," "Missing Identity," and "Life Insurance."
SpongeBob's alarm clock shows signs of sentience and nearly loses its energy, as evidenced by its coughing from a lack of oxygen due to Gary chewing on it among other things in SpongeBob's house. SpongeBob uses duct tape to fix it, but the alarm clock just falls backward.
SpongeBob turns up the volume on his alarm clock and sets it to the waking hour in an attempt to wake Patrick from sleepwalking. The noise is so loud that it wakes several citizens up and causes worms to start barking, however it fails to cause any effect on Patrick, as he continues sleepwalking.
When everyone investigates what happened to SpongeBob, it turns out that he overslept due to his alarm clock being unplugged. He tries to plug it in, but the clock falls over and starts bouncing around, eventually destroying itself.
Later, SpongeBob tries to reassemble his clock. Patrick notices what SpongeBob is doing and tries to help, but gets frustrated and destroys it even further. SpongeBob takes the remains to Clock World and tries to get it replaced, but the owner reveals that his model of alarm clock isn't produced anymore. SpongeBob buys various other clocks to replace his old one.
Near the episode's end, Patrick reveals to SpongeBob that he has shoddily fixed the alarm clock. The next morning, the alarm clock sounds and wakes SpongeBob up, and it's shown that Patrick is in the clock making the blaring sound.
