The story starts when the Pokemon gang arrive in a small town (in which I don't know how to call it) and there's a Ping Pong Tournement featuring Ping Pong Master O. When they arrived at the outdoor Tournement, they see O alright, but they also see a suprise next to him.......none other than Dawn's girl Ambipom!
Ambipom sees the gang after they sent out all of their Pokemon to play outside of the Tournement. She asked O if she could play with them and he allows her to. She joyfully skips to the Pokemon and spotted Ash's Buizel. She secretly has feelings for Buizel and will decide to let it out to him today. When Ambipom was about to walk to him to tell him how she feels, she sees Dawn's Pachirisu next to him. Ambipom's confused. "What's going on?" she asked herself.
Buizel and Pachirisu are just sitting there, then looked at eachother. "Pachirisu, We had a awesome time together." Buizel says to Pachirisu. She agrees, "We sure did, Buizel." "Pachirisu, may I ask for-" "For what?" "A kiss?" Pachirisu blushed, and Ambipom's shocked speechless. "Y-yes...." And the nightmare to Ambipom begins. Buizel and pachirisu leaned to eachother and kissed. Gliscor sees that and yells out "Buizel and pachirisu sitting next to a tree! K.I.S.S.I.N.-" Buizel and Pachirisu punched it (what? I still don't know Gliscor's gender!) to a tree. They stopped kissing when that happened. "QUIT IT!!!" yells Buizel. "YEAH!" Pachirisu agrees.
Back to Ambipom. When she saw Buizel and Pachirisu kiss, her heart breaks, and sits on top of a rock crying. Suddenly, from the Pokemon group, Ash's Monferno walks to her. "Ambipom....are you ok?" he asked. When Ambipom sees him, she stopped crying and her heart's starting to heal, because she realized Monferno evolved from a Chimchar, and that he now might be the one for her, instead of Buizel.
"Monferno.....Chimchar?! H-How did you evolve?" Ambipom asked. Monferno answered, "The 6-on-6 battle with Paul. I was the last Pokemon, and against Electabuzz, when I evolved. Sadly, I lost against him and was badly injured. So were all of Ash's Pokemon including his Pikachu, beside me." He continues, "But we're all better now. Ambipom...." He starts blushing, "How's the Ping Pong Training Center in Vermillion City?" "YOU HEARD?" Ambipom cried. "Yep. Ash told me." Monferno answered. She blushes so deep, her face becomes pink. "Anyway....I-It's awesome. I have the feeling I will become a Ping Pong Champion above all Pokemon!" she says.
Monferno becomes suprised. "That's great, Ambipom!......Ambipom? May I ask you something?" he replied and asked. "Oh, I want to ask you something too!" she replies. They both said "yes." And, suprisingly, they both asked at the same time, "Do you like me?" After it let out, they both blushed deeply. They both nervously letted out a "yes."
They blushed passionately. Ambipom whispers, "Monferno...." "Ambipom...." Monferno whispered also. Then they leaned close to eachother. Eyes closed. They kissed.
While that moment, the rest of the Pokemon crew, even Buizel and Pachirisu, went in a full circle around Ambipom and Monferno. Gliscor almost let out a "Monferno and Ambipom sitting on a tr- rock! K.I.S.S.I.N.G." but it won't because it's afraid they will punch it, plus afraid that Piplup will Bubblebeam it when it let it out. Oh, about Piplup, he now got heartbroken from both a Marill AND Ambipom. He pretty much has feelings for her, too, but since she and Monferno are together, it's too late for him. But he'll get over it. Someday he WILL find love!
And so, Ambipom and Monferno are together. During the whole Ping Pong Tournement and the after-Tournement festival, Ambipom, Monferno, and the whole Pokemon crew spent the time having fun, celebrating the 1-day reunion with their friend Ambipom. Ambipom and Monferno spent their time together, holding hands and looking at the sky and the sunset. But then it's time for her to leave back to the Ping Pong Training Center with O. That's when she had to say goodbye to everyone, and especially to Monferno. They gave eachother a goodbye kiss and she takes the bus back to Kanto, to Vermillion City. "I will never forget you.....Ambipom...." Monferno thought.
Afterward, Ash, Dawn, and Brock returned all of their Pokemon except Pikachu (of course) and Buneary (she wants to spend time with Pikachu) and they move on. The Sinnoh Journey to the Sinnoh Pokemon League and the Sinnoh Grand Festival (for Dawn) continues!
