Bloody stool or just from koolaid?!

My son is 17 months and still breastfeeds more then he eats table foods so his poop is usually runny and yellow. Well today he had 2 koolaid jammers and I just changed him and seen this... I freaked out then calmed down and thought it’s most likely from the koolaid. Should I take him to the doctor to be safe, keep an eye on it or should I not be concerned at all? I know it’s probably the koolaid but I’m still a tad freaked out. (Ignored the sunflower seeds, he had some while playing outside 😅)
