Ikachan (いかちゃん) is a freeware video game created by Japanese developer Daisuke Amaya, under the art name Pixel.

In the game, the player plays a squid named Ikachan, who swims through a cave, meeting and helping other creatures.

As such, the inhabitants of the cave ran out of food and were required to carry pearls marking their allegiance to Ironhead.

[7] After Cave Story's success on WiiWare, Nicalis hinted at ports of Ikachan and Guxt, other freeware games by Pixel, for DSiWare.

[12] MTV's Jason Cirpriano stated that the game would appeal to fans of Cave Story, but also noted that it could be completed in about an hour.
