In How to Fish, Dazed Games’ Steam co-op shooter-fishing game, eat a mini-boss by buying the Beginner Boss Lure on island 2, killing the mini-boss it summons, burning it solid black on a grill, and then eating it.
How to Fish is Dazed Games’ 1-4 player physics fishing game on Steam, and despite the name it is also a shooter where you kill sea creatures, upgrade a boat, and take down bosses. One of its odder achievements asks you to eat a mini-boss whole. It is a quick job once you know the route, and if you handle it right you can knock out two achievements with a single bite.
What eating a mini-boss gets you
Key Eating a mini-boss pops Competitive eating. The trick is that the very same bite can also unlock Yummy in my tummy, which is awarded for eating a burnt creature. Burn the mini-boss solid black before you eat it and both achievements fire at once, so there is no reason to do this twice.

What you need before summoning one
| Need | How to get it |
|---|---|
| Beginner Boss Lure ($40) | Buy it from the shop on island 2 |
| Grill access | Finish the Grillmaster quest on island 3 |
| Weapons and cooked fish | A decent gun for the kill, cooked fish on hand to heal |
This is a short errand, but it depends on a few things being in place first. You need to reach island 2, since that is the only place that sells the cheapest mini-boss summon in the game. You need grill access to char the creature, which is earned on island 3 by completing the Grillmaster quest. And you need enough firepower and healing to win the fight, so keep cooked fish in your pockets to heal through it. The lure runs $40 on a multiplayer run.
Buy the Beginner Boss Lure

Grab it from the island 2 shop for $40 — it is the cheapest mini-boss summon and its fight is the easiest.
Summon the mini-boss

Use the lure to fish up the mini-boss, then fight it.
Kill it

Bring it down with your gun and eat cooked fish to heal if it hits back.
Take it to a grill

Carry the dead creature over to a grill you have access to.
Burn it solid black

Hold it over the flame until it turns solid black, not the usual golden cook.
Check the cook if you want

Press F while it cooks to watch the cooking multiplier fall all the way to 0.
Eat it


Once it is fully burnt, eat it to pop Competitive eating and Yummy in my tummy together.
Burn it solid black before eating — a black creature at 0 cooking multiplier is what unlocks both achievements in one bite.
Mistakes that keep the achievement from popping
The instinct built up over the whole game works against you here. Normal cooking climbs to a 1.5x value multiplier and you are meant to pull items at that peak for money — a burnt creature is worthless and heals almost nothing. For this achievement you want exactly the opposite: keep the creature on the flame past 1.5x until it goes solid black and the multiplier collapses to 0.
One other snag: mini-boss lures have a chance to break on use and vanish in a puff of smoke. If yours breaks before you land the summon, you will need to buy another before you can try again.
