Star walked around the Diaz Household until she spotted something on top of the fridge: a cookie jar. However, no matter how hard she tried, she couldn't reach it on her own.
Soon enough, she got an idea and shifted her arms and bones so they would extend far enough to let her reach the cookie jar. However, once she tried to take the jar, the extended arms made it difficult for Star to back away properly, and she eventually tripped and hit the ground, causing the jar to crack.
Shortly afterwards, Marco came in and, completely unfazed by the sight, simply asked her, "You shapeshifted, didn't you?"
"I'd rather say I armshifted, since I only shifted my arms." Star explained. "Can you help me?"
Marco pinched his nose before helping the princess.
