While Split Fiction offers a relatively straightforward and linear co-op adventure, there are numerous opportunities to explore alternative paths and engage in what the game refers to as Side Stories. Although these are technically optional, they house some of the game’s most memorable moments. For instance, you might transform into pigs or participate in a high-stakes game show. Completing all 12 Side Stories unlocks an achievement, ensuring you experience everything the game has to offer. Here’s how to locate each one:
Legend of the Sandfish
The first Side Story in Split Fiction appears naturally in Chapter 2 following the Rush Hour section. There’s no missing it.

Also in Chapter 2, under the Big City Life section, you'll discover this Side Story near the Port-A-Pottys. Have Mio hop inside one, then use Zoe to toss her to a ledge with a ladder. Lower the ladder to access it.
