Fishin: Impossible is a Caltrop Core game, which means it uses a pool of 4-sided dice (d4s). This game is made to be simple to learn and simple to play. It’s designed to introduce anyone to table top role playing games (TTRPGs), no matter your age or experience level.


  • Players: 3-5
  • Time: 2-4 Hours
  • Age: 6+

What do you think your pets do when you’re not home? Have you ever daydreamed they put on an accessory, switch to an undercover persona, and solve top secret missions of their own?

In Fishin: Impossible, that daydream becomes reality! You play as the Buddies, a group of extra special aquatic creatures that usually help the secret agent Siren Squad on their Missions, but also have their own top secret work.

When they’re not on the field, the Sirens think the Buddies are resting up, just like ordinary sea creatures back at Siren HQ – but that’s not true! What do the Buddies really do while the Sirens are away on Missions? Go on Missions of their own!

Fishin: Impossible is a casual, wacky game meant to be played in a single 2 to 4 hour session of play. It’s great for anyone who wants to solve problems with the power of teamwork and learn animal facts through goofy cartoon shenanigans.

Accessories! Catchphrases! Puns! Animal Facts!

If you love the wacky hijinks of Honey Heist,  the adventures of Perry the Platypus from Phineas & Ferb, or the cozy adventures of the Octonauts, you'll love this game!
