2nd Logo (8 November 2013)
Logo: On the white background, the pufferfish from before drops downs and bounces to the center and the same company name appears.

Technique: 2D CGI.

Music/Sounds: The ending part of the music.

Availability: Appeared in Risk of Rain.

3rd Logo (22 July 2016-)
Logo: On the black background, a dark gray rectangle with a round orange fish (similar to the pufferfish from the 1st two logos, but doesn't have spikes, facing left and his eyes are beady black), zooms in. The fish then chuckles, releasing two bubbles in the process, ending with the words "ChuckleFiSH" with "Chuckle" in the sans-serif font and orange "FiSH" in the semi-serif font, stacked together, fading in below.

Technique: 2D CGI.

Music/Sounds: Just the sound of an innocent man chuckling.

Availability: Appeared in Starbound and maybe future games published.
