The Crab wakes up and scampers along the seabed, singing a song. Along the way, he meets various friends such as different fishes, a shark, a turtle, and even a fishing anglerfish at the bottom, all of whom join in and sing along with him. However, the Octopus continues to sleep undisturbed. Determined to wake him up, the friends try their best but end up getting tired and falling asleep themselves. Finally, the Octopus wakes up, only to be surprised to realize that it's already nighttime.
