The Big Brother House has transformed into Old Mc Donald's Farm! The housemates had their share of being farm animals today. Instead of seeing Big Brother's special tasks as hardship the teens saw it as part of their daily play! Cass Ponti of Pinoy Big Brother Season One even dropped in for some feathering fun.

Early this morning, the teens woke up to find another guest inside the house. PBB Season One's appointed kusinera, Cass had cooked a very special breakfast to start their day. The housemates were all excited to meet her, impressed with her cooking skills and beauty. Cass declined to eating breakfast with them because she was currently dieting and was content with just drinking coffee.

After the hearty meal, Cass had a task for the teens which surprised Brenda. The vegetarian looked a bit pasty white when their Ate Cass started demonstrating how to dress a chicken properly. Kim even nudged the shocked Brenda who just muttered a 'Mmm...' to her. Their guest later on learned about Brenda's food preference but this did not make her exempt from the task. And sad to say Brenda also did poorly on the task so Big Brother turned her into a chicken for the day. She had to don on a costume, roll on feathers then walk and cluck like a chicken.

When their Ate Cass left, the house chicken, Brenda was left mulling in the garden. Since it was lunch time, the others thought it best to accompany Brenda outside for her flimsy outfit made her feel cold inside the house. After Big Brother's ration of yummy Chopsuey and Fried Tilapia, Brenda had a change of costume and was given a sarimanok head dress and wings. Kim commented her colors looked like she was part of the Sinulog Festival in Cebu. The Amazing Amerasian joked she looked like 'Super Chicken'. The Chinese Cutie suddenly sang the 'Chicken Dance' song. This gave Kuya an idea, and the song played all-over the house. Kim and Clare danced along with the house chicken and laughed 'til they were exhausted. 

 Kuya then had a Cock-a-doodle-doo Challenge for the other housemates. Brenda's tilaok had to be challenged, With the other housemates as judges, Jam emerged as the cock-a-doodling champion. She then had to take over the house chicken post. Jamilla even had to have a boiled egg inside her mouth. 

Then it was Clare's turn for a challenge! Big Brother had her dress-up as a cowgirl and the housemates as cows. Clare has to gather all her mooing housemates for her to be successful at her task. It was not easy galloping after very frisky and giggly cow housemates. Also add to that a shrilly sarimanok! "Hindi baka ang tingin ko sa inyo, para kayong mga tamaraw." said the very out-of-breath Clare.

Clare and her 'horse' were exhausted in no time. Big Brother admonished for her to make her trusty horse drink in the pool. He even changed her hoop to a more effective roping tool. Soon, Kim and Jamilla were caught by the 'yeahing' cow girl.

Big Brother has started to challenge the housemates individually! How will Clare and Jamilla fare in their tasks? Will the housemates survive his other challenges this week? More to come from the brilliant teens of Pinoy Big Brother! Weeknights after Sa Piling Mo.
