|“||Ha, ha! I'm wearing non-slip shoes so ha!||”|
Non-Slip Shoes So Ha are footwear in BFDI. Based on a line from Flower, they are used to prevent slipping. They were also mentioned in a commercial by Yellow Face. Their design is almost no different from that of a pair of normal, hot-pink flip-flops. However, in Total Firey Points, they resemble boots.
They later appeared in Insectophobe's Nightmare 2 as an item for Yellow Face's advertisement, claiming that they are in style these days, and Flower wears it in Take The Plunge. However, Purple Face interrupted the ad, saying that no one wears them anymore, as they are over two years old. This caused Yellow Face to make a seemingly racist statement out of anxiety. Due to this, Purple Face calls for someone to reject Yellow Face, but he continues with the ad, making Purple Face interrupt him once more. Yellow Face then got angry and consumed Purple Face.
They reappeared in Get to the Top in 500 Steps, where Flower used them to climb the stairs. Their appearance shocked Ruby, Blocky, and Yellow Face. After Flower utilized them to avoid being shoved by Foldy, it prompted Lollipop to state that they were "so 8 years ago," playing on Purple Face's line. Yellow Face then said that Lollipop didn't know anything, referencing her purple color. However, after Flower was knocked over by Dora. the Non-Slip Shoes So Ha fell off her feet when she was caught by Lightning.
- The commercial marks the first time Yellow Face killed someone.
- The commercial is the first appearance of Purple Face.
- This is the first and (so far) only ad to have the item shown in the commercial appear before the advertisement.
- Flower is the only known contestant to have worn them.
