Stomach ache fruit

As you and your friend were wandering through the dense forest, the sound of birds chirping and leaves rustling underfoot filled the air. Your friend, who had been complaining about his hunger for the past hour, suddenly spotted a bush covered in bright red fruits. Without hesitation, he plucked one and took a bite. His face immediately contorted in pain, and he spat out the fruit, exclaiming that it had a strange taste and felt like it was burning his stomach. You were both curious about the fruit and decided to investigate further. As you approached the bush, you noticed a sign warning of the fruit's toxic properties and how it could cause severe stomach aches and even hospitalization in some cases. You quickly informed your friend of the danger and urged him to seek medical attention if he felt any discomfort. From that day on, you both learned the importance of being cautious when exploring nature and always checking for warning signs.
