Drabble #2! Takes place a few years before the series.
The Flynn-Fletchers were on vacation at a beachside resort; there were swimming pools on the plantation.
"Ooh, look! A mini-pool!" Phineas exclaimed, stepping into the water. His parents tried (but failed) to stop him. "Cool, there's even a bench in here."
Onlookers saw the boy's eyes widen and his face contort into a pained and surprised expression. "That is not a mini-pool!" He cried, jumping out of the hot tub. After some consideration, however, he placed his foot back in, then sat down in the water completely. Thoughtfully, he added, "It's so much better."
Phineas's fascination with hot tubs has always intrigued me. Carpe Diem and have a nice day. :)
