Yoshi approached a crate box in front of him. He picked it up, and he felt the heavy weight crush his back. Yoshi gritted his teeth, and he moved slowly down to the right, looking up and seeing a few crater boxes lying on the ground. Yoshi then thought why the crate boxes were like this, and he then got an idea. He placed the crater box he was holding in the empty space, and wiped his forehead, letting out a sigh of relief. The cavern then shook and a hole was formed in the wall ahead of him. Yoshi stood where he was for a few brief seconds, and then went forward into the newly formed hole, determined.

Yoshi noticed that he started to head downhill as he ran further and further into the wall. Yoshi glanced to both his left and right, to notice the scribbles and drawings of ceratopsids marked on the walls. As he turned right, Yoshi stopped, to see a gigantic, underground water reserve ahead him, brightly sparkling. Yoshi took a quick breather, and he then jumped into the water, making a big splash.

The green Yoshisaurus dive under the clean, light-blue water, and he squinted, not wanting water in his eyes. Yoshi swam as fast as he could, cleverly holding his breath within. As Yoshi got closer and closer to the bottom of the gigantic water reserve, Yoshi spotted a few air bubbles nearby. Yoshi opened his mouth and released his long red tongue at one of the air bubbles, grabbed it, and sighed of relief as he breathed within the air bubble that surrounded his head. As he floated in the water, he looked around him to see what it looked like.

Glancing beyond the air bubbles, much to his surprise, Yoshi spotted one of the two dark blue Triceratops skulls. He swam towards it, but was then whacked by the tail of a giant, red-purple electric eel. Yoshi screamed as he was plunged back a few feet, before he swam towards the giant electric eel. The giant electric eel bellowed loudly and shot electric bolts at Yoshi, electrocuting the green Yoshisaurus. As Yoshi fell down to the ground on his body, paralyzed from the shock, The giant electric eel swam towards the wall and dug into it, bellowing as it disappeared into the newly formed crater within the wall.

Yoshi opened his eyes, and took a quick breather. He got up, and noticed the newly formed hole in the wall at the far end of the water reserve from him. Yoshi growled, and he started to swim towards the hole, determined to get the Triceratops skull required to access the possible way to the cruel ruler of the Triceratops Cove. Yoshi eventually made it into the hole, and he slowly turned right as he swam. He looked down to see small, red electric eels squealing for food as he swam, and Yoshi then bumped into the wall. He shook his head, and looked up, to see that the giant electric eel went upwards. Yoshi gulped, and he grabbed the wall, climbing up rather that swimming up, to save up his energy for a possible fight...
