Title screen from Koji the Frog

What did Koji the Frog do to deserve this? All Koji wants to do is eat bugs, and not only does he have to deal with angry bees and cars and lightning strikes, but there’s a gopher underground who’s trying to blow up Koji with dynamite! The gopher can’t sleep through Koji’s incessant hopping, so I understand being annoyed by that, but dynamite seems like a disproportionate response.

Koji seems reassuringly chill about this. He carries the same blank expression throughout the game. Even when he wins, to express his enthusiasm, he holds up a sign that says “Ribbit!”, like a Looney Tunes character. Maybe he’ll get eaten by a snake. It’s all good. He’s Koji the Frog.

Koji’s gonna fall right into that snake’s mouth and enter a world of pain

Besides the unrelenting misfortune that poor Koji has to endure if he wants a meal, the interesting part of Koji the Frog is how Koji moves around. His tongue can stretch out pretty far, but he still has to jump to catch bugs out of the air. Koji’s hop has a wide arc, which can be tricky to line up with the bugs in motion, so you have to lean into his momentum. Plus there’s the gopher, who will blow you up if you stand still for too long (maybe as a homage to the gopher from Caddyshack?). These minor variations – his limited range, his big hops, the homicidal gopher – add a nice twist to this cute, simple game. Otherwise, it gets by on how utterly terrific Koji the Frog himself is.

I expected that developer Marco Carra, operating under the name Slimyfrog Software, would have exclusively made frog-related games, but most of the other titles in the Slimyfrog catalog are desktop utilities, educational tools, or novelty programs (like EarthQuake, a program that shakes the screen around). That means Koji the Frog shoulders the responsibility of being the only frog software produced by Slimyfrog Software. I am happy to confirm that it is certifiably froggy.

A note on versions

The screenshots in this article might look different than the version of Koji the Frog you can find online. Most copies on the internet are version 2.0.1. These screenshots were taken from version 1.0.1, which was included on the demo disc for MacAddict issue #1.

    I’m the original author. It’s amazing to see that Koji is still remembered, even if it’s by only a few of us. It was my first game and knowing people enjoyed it, really makes me happy. 🙂
