In Enma's Vault, there is a crystal called Animal Balistic Gem that turns people into whatever animal that the wielder thinks about. A demon came and stole the crystal without being noticed. Koenma is so informed that crystal is stolen. Koenma soon tells Botan to get Yu Yu Turtle Gang to his office. Botan gets the gang but only 6 were there: Yusuke, Leo, Kurama, Don, Hiei and Raph, the three turtles are in human clothes disguise.

"I'm glad you all are here considering Michelangelo and Kuwabara are doing something else." Koenma says to the 6.

"What do you want, Toddler Breath?" Yusuke asked annoyed.

"A crystal called the Animal Balistic Gem was stolen out of my father's vault."

"What does it look like?" Leo asks.

"It looks like this." Koenma says as he gave picture of the gem that looked like crystal with green and white stripes on it. "And we have a picture of the demon who stole it."

The guys look at the picture. It was a rat demon with gray fur, long rabbit like ears and a tail that looked similar to an otters. Kurama and Hiei instantly knew who it was by the picture.

"This is Snapper the demon vanisher." Kurama tells the others. "He's the only demon that has a power that is similar to a ninja vanishing technique resembling that of our friends the turtles."

"Well, let's go stop the demon before he uses it on people." Raph says as they all left out to find Snapper.

Meanwhile Snapper was holding the Animal Balistic Crystal. Snapper laughed and pointed it at a baby. It glows and a red beam came out and goes toward the baby but a shadow quickly grabs the baby carriage and pulls it next to its mother making the beam miss.

"What happened who moved the baby?" Snapper asks looking around.

"We did!" A voice says.

"Wha…" Snapper says and turns around and see Yusuke and the other behind him. "What the Ninja Turtles and Spirit Detectives, are the ones that moved the baby?"

"Yeah, we did." Raph answers. "Alright, Snapper, we got ya now!"

"Well, you 6…6? I thought there was 8 of you?"

"Sorry, they more important things to do than to stop you." Don says seriously.

"Well, this'll stop you 6." Snapper says pointing to the Animal Balistic Gem that was glowing, and a red beam comes out at the 6.

The 6 boys scream in pain as it infuses them with its power. The stops glowing and the guys come out looking human. Snapper is in shock but he shakes the Animal Balistic Crystal. He sees the 6 get and he runs away.

"See ya, losers." Snapper says vanishing.

"What the hell?" Yusuke asks as he looks at his self and the others.

"We're normal!" Don points out.

"That thing didn't do anything we need to find Snapper!"

"We don't have time, Yusuke." Leo says. "We need to find out what that crystal did to us."

"We can ask the Toddler that!" Yusuke says angrily.

"Well, let's go so we stop the disappearin' rat." Raph says as he stomps off.

But what the 6 didn't know is that they were turning into animals. Soon the 6 got to Spirit World and got to Koenma. Koenma looks and notices that the 6 were not normal Yusuke was a white tiger with his hair on top remaining slicked back but shirt was ripped in half and his jean were ripped at the bottom and his shoe were ripped and completely torn off. Leo was an elephant with his belt and pants but the part where it was crossed with the sword was ripped his arm and leg bands were still on and his bandana was still over his eyes. Kurama was a hyena with his hair remaining the same and his Sensui saga outfit but the arms and legs of the outfit were ripped and shoes were completely off. Don was a monkey with his belt, pants, arm and leg bands and his bandana on his bo however was bigger than him and it hit him on the head. Hiei was an iguana with his hair the same and his cloak on and his shoes were completely off. Raph was a rhino with his belt, pants arm and leg bands and his bandana

"What's wrong, Toddler Breath?" Yusuke says annoyed sitting down.

"Well, you guys are not normal." Koenma says.

"What?" The 6 say in shock.

"We just did a mission and look what happened ta us." Raph points out.

"What you didn't know about Animal Balistic Crystal is that once someone is turn into a animal like you 6 are if you don't break the crystal in 4 hour you stay like that forever."

"What!" Leo, Yusuke and Raph say in shock.

"Then we must go." Kurama says as they all left.

Meanwhile Snapper was robbing a jewelry store he turned all the people into small animals and was taking everything for himself. Snapper laughed mischievously and he heard the door opened.

"Well, well." Snapper says slyly. "The three detectives and the three turtle now animals."

Yusuke growls angrily. "I'm gonna kick your ass!"

"Ooh, I'm scared."

"Well, you should be I mean you're a small animal demon and we're big animals." Don says slyly.

"Not really I've fought bigger." Snapper says slyly.

"Less talk and more action!" Raph says charging at Snapper.

Snapper vanishes as Raph crashed toward the wall with his horn stuck to the wall. Yusuke pounces toward Snapper but Snapper vanishes again causing Yusuke to crash into the ground. Yusuke growls angrily. Hiei tries to grab Snapper but Snapper disappears again.

"Guys, we need a different approach to catching Snapper." Leo says trying to pull Raph out the wall.

"Well, what's ya plan, Leo?" Raph asks as he was out of the horn not broken.

"Actually Kurama has plan."

"Listen…" Kurama says as he whispers the plan to the others.

Snapper was walking out of the jewelry store. He still had the Animal Balistic Crystal in hand and was ready to use it. Snapper soon see a tall shadow and he gets scared that it's one of the Yu Yu Turtle Gang but it was just a statue.

"I'm seeing things." Snapper says but soon hears a roar. "I'm getting out of here."

"Where do think you're going, Snapper." Kurama asks slyly.

"No where…were you the one roaring?"

"Does a hyena roar?"

"No but a…" Snapper says as turned around a pair of eyes and sly smile. "A Tiger does! But I can fix… where did the…"

"Ahhem," Leo says as he had the Animal Balistic Crystal he soon busts the crystal he and the others turn back to normal.

"You won't be able to catch me!" Snapper says vanishing but gets whacked by a bo.

"Nice going, Donny." Yusuke says giving a thumbs up.

"Thanks, let's take Snapper back to Spirit World." Don says as they walk toward Spirit World.
