If the graphics are slow, press the right arrow key several times. Using TurboWarp is also a good option. https://turbowarp.org/1255459225 This is something like a screen of Karen Plankton, who appears in SpongeBob SquarePants. Click the screen or press space key to generate a waveform (no sound). By clicking or pressing the key again, the waveform disappears. Pressing the right arrow key makes this project lighter, but graphics become lower quality. Pressing the left arrow key perform the opposite function. Pressing the up arrow key increases the speed, and pressing the down arrow key decreases it.
By using Fourier series, the waveform motion became closer to the original animation than ver. 1. ver. 1: https://scratch.mit.edu/projects/1249279201 2025/12/24 Speed adjustment function using the up and down arrow keys was added. 2025/12/26 The graphics performance adjustment function using the right and left arrow keys was added. This project was shared on December 20, Karen’s birthday. (It may vary depending on the region.) Credit to Nickelodeon.
