Izzy and Open!
Izzy carried a bag filled with water guns to the park and set it down. She picked out one for herself and filled it with water, then walked to the water fight area. She scanned the area carefully, looking for a good target to soak with her gun or pelt with water balloons. She'd make her cousin Adele proud with her combat skills.
When she spotted an adult with a gun, she sprayed them with water and prepared to run away.
