ZeptoLab

Background: ZeptoLab is a Russian video game company founded in 2008. It's best known for the Cut the Rope series.

(2010-)
Logo: Depending of the variant:
 * Still version: On a white background, we see the logo (in 2017, it's revived). The address and loading bar was seen. On Pudding Monsters, the letter "o" has been replaced with an eye of an eponymous monster.
 * Animated version: On a white background, the green flask zooming in with words "zeptolab" inside it. The bubbles are flying in the flask, forming the back-shadow-zigzag like shape. On Cut the Rope 2, the flask firstly filling in before animation starts.

Technique: Still version has none (except for loading bar). Animated variant has everything.

Music/Sounds: Animated variant has bubble sound.

Availability: Current. Was first seen on Cut the Rope. Then, on Cut the Rope: Experiments, and Cut the Rope: Time Travel. Also appeared on King of Thieves, My Om Nom, and CATS: Crash Arena Turbo Stars. The animated variant appeared in game trailers first, then it made it's first game appearance on Cut the Rope 2. In 2017, it strangely appears again on new editions of Cut the Rope instead of the small animated version. The Still version appeared on newer and older games by company. The In-credit variant appears on all seasons of Om Nom Stories.
