Mini bio

How it started.

Karina and Ronald introduced their shared channel in March 2016 with a “What’s in my Mouth” game. The first upload already had the idea that would run through SIS vs BRO: a sister and brother turning a simple game into a competition.

The videos fans grew up with.

Their early hits included the 2017 Pancake Art Challenge and 2018’s Making Giant Slime Bubbles, where six colors of glue became a slime competition. Their video playlists also span school routines, outfit swaps, mystery-wheel games and funny skits.

Growing with the channel.

In 2024, the siblings released new food challenges and recreated an earlier favorite in “5 Years Later Recreating Our Most Popular Video.” The 2025 uploads include travel vlogs and a tour of their new house, giving longtime viewers a look at their lives beyond the challenge table.
