There are many side quests in Lost in Random but you won't come across them until you arrive in Two-Town, the second world after the Valley of Dice. Here you will come across many NPCs and some will request your help.
One such NPC is the potion maker who is located in Two-Town's Square. Once you enter the square, simply head left and you will see the NPC with a green question mark. The NPC suffers from an extreme split personality, named Jared and Jored, and both sides want peace.
You will be tasked with retrieving three bloobs and giving them to either the emotional side or the logical side. Ultimately, it doesn't matter which side you choose as the reward is the same for both. Both give you the card Natalya's Bell. This defense card will summon a healing bell that will heal Even when she is nearby.
To find the bloobs, you will need to explore Two-Town. To get the first bloob, head back to the beginning of Seller Street. The bloob is located on a staircase that you cannot climb.
To find the second bloob, continue down Seller Street towards Two-Town Square. This will bring you to Scoundrel's Alley. On your right is a pathway leading up and just past that is a ladder. Climb the ladder and you will find yourself face to face with the bloob on a crate.
The final bloob will be located in Two-Town Square. It is almost directly across from where the potion maker is located. You will see a pathway leading up. Take this and you will find the bloob sitting on a rooftop.
The bloobs also yell loudly as you get close, alerting you to their position. With all three bloobs in hand, return to the potion maker and make your choice. As stated earlier, the decision doesn't make much of a difference.
