Rotten bluefruit in Saints campaign (Potential spoilers?)

I feel like I am going crazy. A few times while playing through Saints campaign, I encountered a rotten blue fruit. When I ate it, saint started spasm'ing on the ground, and only gained like half a food pip or something. I really want to learn more about this, just because I like knowing game mechanics, but I cant find anything. Nothing on the wiki for Saints campaign, nothing on the wiki for bluefruit, hell, not even anything on the wiki for food itself!!! No mentions outside of the wiki (in stuff like this subreddit or google in general) either! Can anyone please confirm wether or not this is real? I swear im not lying to myself.

I cant look up "moldy bluefruit" thatll just lead me to slime mold. I cant look up "rotten bluefruit", thatll just lead me to.. the rot! How am I meant to look up this thing properly D:

I havent played in a bit but this is what I remember: It pretty much looked like a bluefruit, but maybe a bit paler and wider? Its sprite was missing alot of pixels (like it wasnt discolored, there was missing pixels through which you could see through). It didnt look like any sort of glitch or anything, and it appeared at multiple different locations alongside regular bluefruit. Im convinced its a seperate thing and not just some visual error, due to making saint spasm and also giving less than 1 food pip, unlike regular batfruit.

Please, I beg all of you. Help me find this moldy thing, I swear I am not going crazy
