The Heroes were in the frozen treetops, knocking down Kritters and Armies along the way and found Winky the Frog which carries the kongs throughout the treetops.
"You kongs seem to be friends with this frog." Popo said.
"Of course, Popo. We have animal friends living on the island, helping us against the Kremling Krew." Diddy Kong said.
"You kongs never cease to amaze me." Megumi said.
"I wish that there are more animals in this island that are friendly and not working for the Kremling Krew though." Donkey Kong said.
"Don't worry, Donkey Kong. You still have us as your friends." Mario reassured as he put his hand on Donkey Kong's shoulder.
"Aww. Thanks Mario." Donkey Kong said, smiling.
They then entered a cave which was too dark to see.
"It's pitch black in here." Tia said.
"I can't see a thing." Kanchome shivered.
"Oof! I think I hit something." Ness said.
"That was my butt, you touched, Ness." Jeff said.
"Whoops, sorry." Ness nervously chuckled.
Just then a green parrot carrying a flashlight flew into the hero's view.
"Bawk. Hello Donkey Kong and Diddy Kong and Universal Heroes. I've come here to light the way for you guys to see." The green parrot said.
"Thanks Squawks. We really needed a flashlight to see in the dark." Donkey Kong said.
The heroes traveled through the dark cave with Squawks the Parrot lighting up the pathway.
They came across some kind of drums that are spewing out fire that says; 'OIL' on the front.
"Boy, does looking at these things bring back memories." Mario cooed, remembering a very long time ago seeing these Oil Drums when he had to rescue his ex-girlfriend, Pauline from Cranky Kong who was the original Donkey Kong.
"Um...yeah. Cranky Kong, once explained to me and Diddy Kong about these Oil Drums during his time against you, Mario." Donkey Kong said.
The Heroes traveled further into the caves taking out Krushas and Klumps in their path while avoiding what seems to be spiked wheel tires, called Mincers that rolled at them, but they jumped over them and exited the cave.
The heroes entered the boss arena.
"I wonder which boss we're up against this time?" Red Link wondered, getting prepared.
"Whatever it is, it better get ready for a serious butt kicking!" Mighty Ray said.
Just then a gigantic beaver that resembled Very Gnawty back at Kongo Jungle, but instead of having a brown fur color, this beaver had gray fur appeared. This was Really Gnawty who seems to be much stronger than Very Gnawty.
"Huh? Is it just me, or are we facing the same beaver again?" Blue Link asked.
"Poyo Poyo Poyo." Kirby wasn't sure if that's the same beaver they encountered before.
"No. It's not Very Gnawty, that's Really Gnawty! He's much stronger than Very Gnawty! Here he comes!" Meta Knight warned.
(Heroes vs Really Gnawty)
(Cue-Sonic Adventure 2- Egg Golem)
Really Gnawty glared at the Heroes and jumped at them, but they dodged Really Gnawty, making him pound the ground, causing the stalactites to fall down on the Heroes.
"Whoa! Look out, everyone!" Ribbon shouted out as everyone avoided the sharp dangerous stalactites that were raining down on the ground.
"Be very careful everyone. This battle is much harder than the one with Very Gnawty." Tiff warned.
Really Gnawty jumped at the Heroes with very fast speed, making it harder for them to land a hit on him.
"This bushy tailed furball is also much faster than that other rodent back at the Kongo Jungle. It's time to charge him for this." Mighty Ray said as he took out a banana and groaned in disgust at it as he pinched his nose before swallowing the fruit, causing his eyes to spark. I'M MIGHTY RAY! FEAR MY EYEBALLS!" Mighty Ray shouted his catchphrase before firing electricity at Really Gnawty, zapping the giant beaver as his skeleton started showing.
Really Gnawty then jumped into the air in anger from getting electrocuted and pound the ground sending the stalactites falling down on the Heroes again as they managed to dodge them again.
Really Gnawty then looked at Kirby and decided to head towards the young star warrior.
"Watch out, Kirby!" Meta Knight warned.
Kirby glared at the evil beaver as he got out his hammer and swung it at Really Gnawty's chin, causing him to whimper in pain from the impact as Yellow Kirby took out a dark red bandana and inhaled it.
(Cue- Kirby Right Back At Ya- Kirby Transformation)
Yellow Kirby did the 'Kirby Right Back At Ya' copy ability style and his dark red bandana tangled itself around his body, making Yellow Kirby backdrop around, trying to get himself untangled and succeed as he managed to place his bandana on his head.
Tiff, Tuff, Fololo and Falala were in awe as they saw that this ability was different from Fighter Kirby.
"What's that, Meta Knight?" Tuff wanted to know.
"Yellow Kirby has transformed into Backdrop Kirby." Meta Knight said.
Backdrop Yellow Kirby grabbed Really Gnawty by the tail and backdropped him into the ground on his head, before picking him up again and slamming him frontwards this time.
Really Gnawty recovered as he got up and lunged at Lin Chung, who shot his projectiles from his staff at him. But the beaver smacked them away with his tail and tried to bite into Lin Chung's head, but the warrior managed to jumped out of the way in time, making Really Gnawty gnaw into the ground instead, giving Lin Chung an opportunity to bash Really Gnawty's head into the ground with his staff.
Jumpy Ghostface wrapped his rope around Really Gnawty's body and tossed most of his carrot grenades at him, burning him from the explosions.
"Way to go, Jumpy Ghostface. Let's show this overgrowth rat what happens when he doesn't behave himself." Sonic snickered as he turn into a ball and started spin dashing into Really Gnawty's face multiple times.
Knuckles threw a hard punch into Really Gnawty's stomach, causing the beaver to wail in pain from the echidna's hard punches.
Really Gnawty got up from the ground and broke free from Jumpy Ghostface's rope and was furious as he was determined to finish these heroes off.
"Looks like beaver boy is getting serious. Time to take him down!" Diddy Kong smirked as he jumped on top of Really Gnawty's head like a trampoline, knocking the beaver down a little and kicking him in the back of the head.
Link down thrust his sword on Really Gnawty's tail, making the beaver screech in pain.
"Alright, Zatch, Let's finish this." Kiyo said.
"You two, Tia!" Megumi said.
Zatch and Tia began to charge up their spells.
Ness, Paula and Poo charged up their PSI moves.
Mario and Luigi charged up their fire powers.
Ben Tennyson who was still in his Heatblast form charged up his fire power.
Aelita charged up her Energy Fields.
Odd loaded up his Laser Arrows.
Popo and Nana charged up their Blizzard attack.
"Zaker!" Kiyo Shouted as Zatch fired a blast of electricity from his mouth.
"Saisu!" Megumi called out as Tia moved her arms back and threw a crescent of energy at Really Gnawty.
Heatblast sent out a blast of fire.
Popo and Nana fired their blizzards.
Ness, Paula and Poo fired their PK Flash.
All of the blast of energy struck Really Gnawty, making the beaver screech in pain and agony from all the attacks striking him at once as Donkey Kong finished him off with a punch.
Really Gnawty was down for the count.
"We did it!" Jeff cheered.
"That beaver was pretty tough." Tiff remarked.
"That was pretty awesome how we did a combination attack on that rodent." Heatblast cheered as he reverted back into the Ben Tennyson.
"You guys sure showed that rodent who's boss." Ribbon congratulated.
The heroes did their victory dance.
(Cue-Super Smash Bros 64-Ness Victory Theme)
The golden banana fell from Really Gnawty who was lying unconscious on the ground.
"That's the fourth banana we have now." Donkey Kong said.
Just then Cranky Kong walks into the view.
"Are my old eyes playing tricks? I'm sure I have seen that beaver before? Where could it have been?" Cranky Kong wondered.
"That wasn't the same beaver before, Cranky. This beaver was pretty tough." Link said.
"But that overgrown furball was no match for us." Odd smiled.
"Grab the banana and give it to me. Head down the mountain to the factory." Cranky Kong said.
The heroes were astonished.
"Factory. What factory?" Diddy demanded to know.
"The Kremling Krew are making a factory on our island along with some other people." Cranky Kong explained.
"That's not good! If that factory isn't shut down, it could ruin the whole environment and population on this island!" Tails said.
"We must shut down that Kremling factory then. Let's go, everyone." Donkey Kong said.
The heroes left the Gorilla Glacier and headed off to the factory.
