In The Astro Mega ship

Cassie is in the Main area of the Astro Mega Ship cooking up some food while the other Rangers were out doing a mission. She opted out of said mission in order to work on some school work which she had already completed faster then she had expected. The Rangers wouldn't be back from there trip for at least another Hour and an Half. Cassie was about to head to the Training room as theres no such thing as getting to prepared for battle when your battling to save the Word. When walking down the hallway Cassie hears a noise from the main Area. Hmm thats wired I just lefted there what can be making that noise? wondered Cassie as she turned around to check on what had just made that noise.
