I do not own Pokemon Mystery Dungeon.
Kangaskhan blew out a long sigh. Things were dull without Team Pokepals here. The worry about the spreading of stopped time was worrying the whole town. She had been busy the whole day with people storing valuables and taking them back out. She went into the back to check something. She notice one of the storage boxes give a short glow before going out again, much like when a team accessed their storage from a Kangaskhan Rock. What was surprising, is whose box it was. She walked over and looked at the box. It was Team Pokepals. Kangaskhan didn't know whether to cry or shout with relief. Team Pokepals was alive! Thinking to herself, she decided to wait. She didn't want to raise anyone's hopes about them being alive. She walked back out and carefully closed the door behind her. "You two better come back." And with that she went to deal with her next customer.
Later in Wigglytuff's Guild...
"They're still alive. Hope you come back alright friendly friends!"
A/N: Okay I know it's a little far fetched but it seems likely that Kangaskhan would know the storage was used and would be able to tell it the team was alive in the future when they put new items in. I mean you have access to all of you items from the past, so it makes for a good theory.
