The second week inside the Pinoy Big Brother: Celebrity Collab Edition 2.0 house took an unexpected and nostalgic turn when the housemates woke up to a sound that could only mean one thing — a school bell. What began as a puzzling wake-up call quickly transformed into one of the most entertaining episodes yet, all thanks to the return of a familiar and much-loved personality: Esnyr Ranollo, the PBB Collab third big placer turned viral comedic sensation.

A “classroom” reunion inside Kuya’s house

When Big Brother summoned the housemates to the living room, confusion turned to laughter as the mystery guest was revealed. To the delight of fans and housemates alike, Esnyr made his grand reentrance — this time not as himself but as his iconic alter ego, Ma’am Castro, the no-nonsense but endlessly funny teacher from his viral “Esnyr University” skits.

Esnyr’s comedic transformation instantly brought new life into the house. Complete with his signature glasses, teacherly tone, and witty one-liners, Ma’am Castro took charge of the classroom that was once a house, setting the tone for a day filled with lessons, laughter, and friendly chaos.

“Class, good morning! I am your new principal,” he proudly declared, as the housemates — both Kapamilya and Kapuso — burst into applause and excitement.

From influencer to role model

Esnyr’s return marked more than a fun crossover between his online persona and the PBB universe — it was a full-circle moment. From his early days as a TikTok content creator known for his classroom comedy, Esnyr has grown into a multifaceted artist and youth figure. His signature humor, built on relatable student life experiences, resonates deeply with a generation that finds both laughter and comfort in nostalgia.

Now, bringing Ma’am Castro into PBB was not just for comic relief. It symbolized Esnyr’s unique gift: blending humor with heart and turning everyday moments into opportunities for connection.

Lessons from Ma’am Castro: Cleanliness, camaraderie, and character

As the self-appointed “principal” of Kuya’s new school setup, Ma’am Castro did not waste time enforcing her first lesson — discipline. Upon inspecting the bedrooms, she was horrified by the housemates’ cluttered spaces. With exaggerated exasperation, she jokingly scolded them for the “storm” that seemed to have swept through both the boys’ and girls’ quarters.

Her comedic tirade, however, came with a meaningful reminder: cleanliness is part of responsibility. The housemates promised to do better — Joaquin Arce assured that they would organize their things once their luggage was returned, while Lee Victor vowed to take charge of the laundry.

It was classic Esnyr — humor that makes you laugh first and reflect later.

“Reverse class picture”: A new kind of classroom challenge

After setting the tone, Ma’am Castro led the housemates to their first major group task — “Reverse Class Picture” — where strategy and teamwork met school-day nostalgia. The challenge required housemates to dodge the frame as Ma’am Castro, blindfolded, snapped random photos. Anyone caught in the photo would be eliminated from the round.

The game produced hilarious and heart-pounding moments, with housemates scrambling, hiding, and laughing in equal measure. By the end, five winners emerged as group leaders: Anton Vinzon, Krystal Mejes, Carmelle Collado, Reich Lim, and Miguel Vergara — each set to form their own four-member teams composed of two Kapamilya and two Kapuso housemates.

These teams, Kuya revealed, would share not just challenges but nominations and victories throughout the season — making the school-themed twist a major turning point in PBB Collab 2.0.

A scene-stealer and a symbol of joy

Esnyr Ranollo’s appearance proved why he remains one of PBB’s most beloved alumni. His quick wit, unfiltered charm, and genuine warmth brought a refreshing energy that reminded viewers why the show has endured for decades — it is about people, stories, and moments that feel real.

Beyond the laughs, Esnyr’s comeback as Ma’am Castro highlighted his growth — from a content creator to a performer capable of bridging entertainment and empathy. His humor continues to celebrate authenticity and Filipino youth culture, proving that laughter truly is a universal language.

As the “students” of PBB Collab 2.0 prepare for more lessons and challenges under Kuya’s unpredictable rules, one thing is certain: Esnyr Ranollo’s “school visit” will not soon be forgotten.

With Ma’am Castro’s trademark sass and wisdom echoing through the PBB house, class is officially back in session — and the world is once again reminded why Esnyr’s humor, much like his heart, deserves an A+.
