Disgusting Oozeling

I was collecting herbs in the Plaguelands and got attacked by those pesty slimes. To my surprise *cough* the slime drops an Oozing Bag. Inside this bag i found a Disgusting Oozeling. This small new pet follows me around since... The debuff is quite funny because a lot of people passing by try to cure you. Also the Oozeling is running beside or next to you instead of behind, like most other pets.
