This is another part of a half-trade with  Dragonballfan 's. This time is with "Agumon getting air inflated by a pump by an unspecting Guilmon who didn't notice."
The small story that I thought of was Agumon and Guilmon are doing a side job at the Park for balloons, and They are both starting to pump up the balloons, a half-hour ago, they were almost done and they just need to start up one more balloons and someone was yelling to Guilmon. He turns around to knows what it is, and he accidentally put the tube to Agumon and set the Helium to Full Blast, leaving Agumon to a large over sized balloon for attracting customers.
