Last part recap: Mine and Tk's Digimon digivolved into their champion levels and defeated Devimon which cost them their data which turned them into their digieggs. Then we got a holographic message from a mysterious person named Gennai. Now we have to go look for the tags and crests to make our Digimon digivolve further to their Ultimates.

We were at a beach near infinity mountain and Tai was saying that we should build a raft and float to Server. Matt and the others actually agreed with him. I had to agree, because Tai's my older brother. So we were busy gathering supplies to build our raft. That's when Leomon asked if we needed help. He gathered all of our Digimon friends. Soon our raft was finished. We said goodbye to our friends and hugged Leomon. Me and Tk didn't know that we would see Leomon after we beat Devimon. All of a sudden, a giant whale swallowed us.

A giant whale swallowed us and Izzy saw a black gear stuck in his belly. Palmon destroyed it using her poison ivy attack. All of a sudden, there was a low rumbling. "Thank you Digidestined for removing the black gear stuck in my belly. I am Whamon, I will take you anywhere." "Oh cool, can you please take us to Server?" I asked. "Yes." He said.

Digimon analysis: Whamon is a Sea Animal type Digimon. It lives in the deep oceans of Net, and has a large build. Watch out for it's tidal wave attack​. Whamon is brown and blue.

Whamon gave us a ride to Server. "Thank you Whamon." We said. "You are more than welcome Digidestined." Whamon said. "I never thought I'd be riding in a giant whale." Joe said. All of a sudden, Tk and Karina's​ digieggs hatched. Tk's Digiegg hatched into a little white squishy thing. Karina's digiegg hatched into a little pink and purple pup with white ears. "Our digieggs hatched!!!" Karina and TK said. "Is that a mini mart?" Mimi asked. "Let's go see if our tags or anything​ are in it." Tai said. We walked into the mini mart and were looking around for our tags or crests. "I found a chest you guys." Tk said. "Good job Tk, let's open it." I said. We opened it and saw our tags. "Awesome, now we just have to find our crests." Tai said as he picked up his tag and put it around his neck.
The Digidestined have now found their tags. All they need to do now is find their crests. Will they find their crests and have their Digimon digivolve into their Ultimates? Find out in the next part of Digimon Adventure 3...
