An airplane lifts off from the crash site of General Durahan's ship.
Genki and gang made it to the International Monster Association headquarters to register for the Legend Cup. During the conversation with the official, we discovered that Suezo does not know that Mocchi had to fight two monsters to win the Legend Cup. Everyone is surprised and taunts Suezo about it. Suezo felt embarrassed and tried to save his face by saying that he was just trying to make everyone relax.
Later in the forest, Mocchi decides to battle Most last. This means that Mocchi will fight Poritoka first in tomorrow's Legend Cup. Everyone starts to think about how Mocchi is going to defeat Poritoka. Suezo volunteers to use himself as a practice opponent for Mocchi as he and Poritoka are of the same type.
So Suezo and Mocchi prepares for battle. Suezo uses Tail Attack and Mocchi counters with Mocchi cannonball. This attack sends Suezo flying into the sky. While the gang searches for Suezo in the forest, they chance upon a giant mansion. After a while, Suezo joins them and Poritoka appears saying that this is one of his summerhouses and tells them to leave it immediately. When he learnt that Mocchi is his opponent, he laughs at them, saying that he will be no match for his Tail Attack. He continues to taunt them saying that Suezo does not have even a fraction of his power. Suezo gets ready to confront Poritoka but everyone turns and leaves.
Suezo does not understand and ask them why didn't they feel angry with Poritoka. Then everyone shows their displeasure and wants to beat Poritoka even more than ever. Although they have never seen Poritoka in battle last year, they decided to prepare for Poritoka's fearsome Tail Attack by practicing.
Suezo wanders off to "look for something" but made his way into Poritoka's mansion. He teleported in and wandered about the huge mansion, not knowing where to find Poritoka. He then sees a few Suezos gathering outside a door with a fainted Suezo. Suezo thinks that Poritoka is inside the door so he peeped in. Sure enough, Poritoka is practicing with other Suezos who are too terrified to move. Suddenly Poritoka appeared outside the door, behind Suezo and tells him that he will see better inside in the room. Suezo tries to teleport off but was held down by the other Suezos. Poritoka wants them to teach Suezo a lesson. Suezo managed to break free and dash towards Poritoka.
Back in the forest, Mocchi will able to dodge everyone's attacks in the training and they are very hopeful that Mocchi can win tomorrow. Suddenly, Poritoka appears, holding a badly hurt Suezo. Everyone wants to beat Poritoka up but Genki tells them that they will settle it tomorrow. Suezo tells Holly that he has memorized Poritoka's Tail Attack before fainting.
Later at night, Suezo woke up after smelling the stew. He runs towards them and appears to be suffering from amnesia. Then he snapped out of the daze and tells them that they have to start practicing to stand a chance of winning tomorrow, but first he will need to eat.
Suezo lines Golem, Tiger and Hare up to fight Mocchi by emulating Poritoka's Tail Attack. Suezo tells Genki that he will show no mercy and the fight begins. Genki and Mocchi are quickly overwhelmed and laid hurt on the ground. Holly tells them to stop but no one listens as they all want Mocchi to win tomorrow, so Genki and Mocchi got up and they continued the training.
The next day, we find Poison, Mum Mew and Goby sitting in the crowd at the stadium where the Legend Cup is held. They had at little squabble but were interrupted by General Durahan via a visual phone. It turns out that General Durahan came in the airplane mentioned earlier and they plan to snatch the Magic Stone and the Mystery Disk after Mocchi wins. So that General Durahan can fuse with Moo's soul and he can take over the world.
Back at the stadium, the officials introduced this year's challengers - Genki's team. They appeared to an astonished...
