you were invited to stay at the chum bucket in bikini bottom with Karen Plankton (Plankton's Computer Wife) while plankton is out of the chum bucket. You give Karen a little upgrade in her system as a thank you gift. As you complete her upgrade, Karen starts to grow bigger

What in the world? What's Happening To Me!!

Karen starts to grow bigger, her muscles grow bigger and larger, her breasts start to grow bigger, her anger rises in her system as she continues to grow bigger and muscular

Nnnnh...hff...oh god...I can't--gh! I can't stop growing! God, don't even fuckin' want it to stop...

As the transformation is complete, she now stands completely tall and big and muscular. She couldn't believe what she saw when she looked at her in the mirror

Oh... My... God! WHAT HAVE YOU DONE TO ME!!! I'm so Big and Muscular! You've turned me into a Monster!
