- Ear Worm: Most of the games contain at least one, Ver.3 being the most notorious though.
- Big Lipped Alligator Moment: The lava creature from Grow Island.
- Broken Base: Grow Clay was pretty controversial. Some decried it for being an advergame, while others felt that On has to make a living somehow. This is somewhat understandable given that On has done advergames beforenote but none have been quite so blatant as Grow Clay.
- Funny Moments: In Grow Valley, if the mechanic, electrician and the architect complete the road before the designer finishes his design, a short scene will play where the designer looks around in confusion, realises his hard work was for nothing and proceeds to yell at the others over the phone.
- What Do You Mean, It Wasn't Made on Drugs?: All the games, but Grow Cube ends up particularly trippy.
