Popo and Ness were both playing tennis with each other in the green grassy meadow of Melee's All Star area, where Shrek was watching the match as he had nothing going on at his swamp. The two kid Smashers were just happy to send some time with each other, even if it was odd that they used equipment that weren't rackets for tennis.
"Say, where has your girlfriend gone?" Ness asked while slamming the green fuzzy tennis ball back with his baseball bat.
"Oh you mean my identical twin? She's having one of those gas related adventures again," Popo responded cooly as he smashed the ball of fuzz using his wooden mallet.
Young Link was walking by drinking some Lon Link Milk, turning his head to spot the Ice Climber winning the tennis match. He smirked as he made his presence known by burping loudly, catching everyone's attention.
"Better out than in, I always say!" Shrek laughed while wrapping his big ogre arms around the back of his green head.
"Haven't seen you cute guys in a while!" Young Link laughed while placing away his milk carton, adjusting his green tunic. "So what's up?"
"Oh we were just trying out tennis." Ness said as he wealked up to the younger incarnation of Link, placing his hands on his hips. "Was there something you wanted to do, Hero of Time?"
"Yeah... I kinda wanted to go on a little journey with you." Young insisted as he stretched his arms. "Ya know like old times!"
"Gee, I'm not sure about it." Popo said as he moved his gloved hands around. "Don't you think we go enough on these stories?"
"Trust me, it'll be great!" The Link of young age insisted as he grabbed Ness and Popo, taking off as he burped goodbye to Shrek, who decided to turn the meadow into a swamp utilizing the fountain in the middle.
Later at the temple, the boys were rushing through the giant maze to reach what was called the pit, where the three found a bunch of unguarded items.
"What should we do with them?" Popo asked while patting his hammer on his parka covered back.
Ness clapped his hands together as his eyes began lighting up. "Maybe we should go and horde them so they can shine on as collectables!"
Young Link had a different mindset, as he smirked upon picking up a beast ball. "Who said anything about storing them...?"
Popo and Ness exchanged confused glances with each other as they watched Young Link giggling in a weird manner, with the green clothed child activating all the items at once. And from that point... things weren't the same.
