Heres chapter 4. So sorry if the update was late my internet connection wasn't working properly :( The next update will be a bit late as I have exams.

"So if captain Kurotsuchi didn't do this then who did?" asked Captain Ukitake. "I can tell you." said the bat "It was the brat from the eleventh division, Yachiru." There was a collective gasp at the statement.

Kenpachi roared at the accusation "How dare you, you stupid clown!" He then leapt towards Kurotsuchi to try and tear him apart. A happy voice that was settled at his shoulder gave a happy screech and said "Yeah Kenny is going to have fun with the clown face." However he couldn't have any fun as Unohana's trunk wrapped around the wolf's waist and pulled him down.

Kenpachi had become a giant wolf with black fur, golden eyes with bells attached to the head. He also had his eye patch on and had a giant scar going down his left eye. "Calm down Kenpachi I believe we should allow Kurotsuchi Taicho to explain himself." ordered the head captain firmly. He then looked up at the bat waiting for him to explain. However before he could do so he was interrupted by a pink colored fox which jumped of Kenpachi's shoulder. "So that's what that weird green liquid did." said the hyperactive vice-captain of the eleventh division.

It was now obvious to everyone that Yachiru had done something that has led to their current predicament but the question was how? To answer the question we have to go back in time.

The Twelfth division Research department, 21:30, Yesterday

Yachiru the hyperactive and sugar happy vice-captain of the eleventh division slowly crept into 'clown faces' laboratory. Despite the high security around the area it was considerably easy for the pink haired girl to creep in there. In fact she was so sneaky she could actually consider a career as a ninja. That aside she was currently high on candy all thanks to a certain terminally ill captain who liked to moon light as Santa. Anyway said girl was trying to find ways to pull pranks on various people. Since the oddest and weirdest gadgets could be found with 'clown face' she had decided to raid his laboratory.

She walked around the place not affected by the tentacles and weird chemicals. "Ken-chan could have a lot of fun here." she thought. As she ambled down an aisle she suddenly came across a table. On it was a bottle of green liquid and a packet filled with green marbles. She opened the packet and promptly put one in her mouth. It tasted sweet and sour. As she sucked on it she tried to open the bottle but was unable to. As she kept trying suddenly the laboratory was filled with light. Someone behind her yelled "Hey put my experiment down you stupid brat!" The owner of the said voice tackled her. Unfortunately for the enraged Kurotsuchi she easily dodged him accidently dropping the bottle which was made out of glass. The bottle shattered on hitting the floor the green liquid spilling out. On contact with the air it started to fume furiously. The fumes rapidly changed color and the vapors became transparent carrying a slight fragrance. Meanwhile Yachiru had perched herself on one of the racks. This rack also happened to be filled with glass bottles containing the same green liquid. In his rage and blinded by the fumes he hurried towards the girl accidentally toppling the rack. All the bottles broke and the liquid started to fume. In the midst of the confusion Yachiru fled carrying the packet of 'candy'.

The Captain's meeting hall, 06:45, Today

"…and while clown face was coughing I took the packet of candy and went away." finished the prodigal vice-captain. When she was done Kurotsuchi spoke up from the ceiling "As the brat narrated it wasn't my fault. The accident happened thanks to her." "Yeah but why did we become animals?" asked Rukia who had been quite happily turned into a black furred rabbit.

Her question was answered by Captain Kurotsuchi.

"A few weeks ago I had Nemu trail after the former second division captain Yoruichi Shionin. I had always been curious about why some of our officers were able to shape shift while some like captain Komamura were anthropomorphized animals. I had Nemu collect samples of DNA from them. A few weeks ago I was able to hit upon a chemical compound that would allow temporary shape shifting. Only thing is it was an extremely weak and volatile liquid that works on people with very high reiatsu. I managed to produce a large amount as I hoped exposing someone with low reiatsu to the gas in an isolated chamber would allow them to shape shift as well. I also managed to concentrate the liquid into a candy like thing for easier consumption. When the pink haired brat broke the whole sample the gas spread all over soul society affecting all the captains and vice captains. However it did not affect Nemu as she is a mod soul and it didn't affect captain Komamura as he is not completely human. However the problem is those who have high reiatsu could permanently turn into animals thanks to the liquid."

The shinigami in the massive hall stood stalk still taking in this new information from the twelfth division captain.
