Dry Bowser, Silver The Hedgehog, Petey Piranha, and Toadette were all facing a gigantic metal crab, which roared loudly as it stood before the Ocean Palace.
"Hillsters, GO!" Silver exclaimed as he pointed at the giant metal crab.
Dry Bowser charged right towards the sea, zapping blue lightning bolts from his skeletal fingertips at the metal crab, with it smashing Dry Bowser into pieces using its right pincer.
Petey roared loudly as he began flying around the metal crab, barfing brown goop onto the mechanical monster. The crab hissed as it grabbed Petey with both of its paws, squeezing him until he literally popped into confetti.
Toadette spun her pink pigtails as she flew into the air, approaching the metal crab as she tried to swoon it over.
"Please stop being so mean, Mr. Giant Metal Crab," Toadette pleaded innocently as she gave the monster big, puppy eyes.
After several seconds of silence, the metal crab smashed Toadette away with its left pincer like a fly.
Silver fired off several green psychic blasts at the metal crab, but they didn't do much as the giant crab literally sat down on Silver, crushing the albino, anthropomorphic hedgehog.
Later in the evening, the unsuccessful Seaside Hillsters returned to their headquarters, with the metal crab continuing its evil reign of terror.
"Ugh... that was embarrassing..." Dry Bowser grumbled as he readjusted his skeletal hand, sighing. "We literally got beat."
"Yeah... our butts were really kicked..." Toadette added in as she rubbed her sore butt with both of her hands, sniffling. "That crab wasn't nice at all."
Petey grumbled in agreement as he was crawling on the floor, unable to get back up after having been popped.
"You're right, Petey. We definitely need to train." Silver agreed as he limped into the living room, holding his injured right arm with his left hand. "Oh, if only we had a fifth member..."
"Excuse me, did you say fifth member?" R.O.B. asked as he rolled up to Silver immediately.
The four Hillsters looked at each other, smiling as they turned back to R.O.B.
The next day, at the exact same spot, the giant mechanical crab was wreaking havoc at the Ocean Palace, with the Seaside Hillsters there to kick his robotic crustacean rear.
"All right, Hillsters, show now mercy!" Silver exclaimed as he immediately fired off green psychic blasts at the crab, hovering in the air.
ROB rode in Petey's pouch as he fired off a charged up pink laser, hitting the crab exactly in the middle, causing it to be stunned. Petey then slammed his head onto the crab, knocking it into the sea as Dry Bowser spun right through it, with Toadette shooting several pebbles at it using her slingshot. The crab, which continued being shot at by Silver and Toadette, suddenly shook violently as it then exploded, with the Hillsters cheering.
"Yeah! That was tight!" Silver exclaimed as he laughed, turning to Petey and ROB. "You know what, R.O.B.? You are an official fifth Seaside Hillster now!"
"That's... good to know." ROB commented in his robotic voice. "That makes me... feel satisfied."
The other four Hillsters cheered as they went to the Ocean Palace Burger Paradise nearby to celebrate.
