Someone who is so unbelievably cute and fun to be around that you wanna squeeze them and play with them in the bushes. They tend to be the same age as you and are usually in college. Ooblecks also tend to have fun with creative activities, and it is in these moments when it is easiest to spot an oobleck. Be warned, after a while of knowing an oobleck, you too will become an oobleck. Transforming into an oobleck is always recommended, but can make focusing on college work more difficult. Occasionally, they are confused for a corn-starch water mixture, but no need for worry. They are still the same old oobleck you know!
