Development
Green Ninja Year of the Frog was announced on January 4th 2015 with a projected release date of early 2015. Jon Annal, the game's artist, pointed out that the background in the preview image on the game's announcement blog post was a rough design and that a decision had not been reached on on what the background would be.

The game was shown, along with Magic Touch Wizard for Hire and Silly Sausage in Meat Land, at the Pocket Gamer connect event that ran from January 13-14, 2015. The game Guardian Rock was used by Aaron Steed (the game's programmer) for research on Green Ninja's game mechanic, Steed also likening Green Ninja to his personal game Flying Kick.

On February 12, 2015 Jon Annal mentioned that he was preparing to use his voice in the game. Two screenshots of the game were shared on April 1st of 2015. By May 1st, 2015 the entire game had been completed, with Nitrome just adjusting the game's levels, animations, sound, and interface, along with drawing the menu. On the same day Nitrome and Jon Annal shared images of a sketch of part of the game's menu that had been drawn by Helm based off of art by Annal. Helm would continue to help with the game the subsequent week while tweaking of the game was done by Jon Annal.

Although the game had a release window of "early 2015", it managed to miss this. Green Ninja: Year of the Frog had been submitted to the Apple App Store and Google Play store by June 1 2015, Jon Annal also sharing some art from the game on his Twitter account.

Trivia

 * Green Ninja was accidentally leaked 6 days early due to a glitch on Nitrome's website which caused their search function to find unreleased blog posts. The post could be found by searching for the word "ninja".
 * The preview screenshot contains a Quackbot from Chisel 2 located in the fire in the background.
