Troubleshooting: When Things Get Sticky

Even the most experienced Keepers run into trouble. Because your pet is a single cell living in a micro-environment, small changes in humidity or cleanliness can have big effects.

Here is the “Emergency Room” guide for your blob.

1. Problem: “Bad” Mold is Growing

You woke up and saw fuzzy white or green hair growing on your oats. This isn’t the good “slime mold”—this is a fungal infection.

• The Cause: Overfeeding or excessive moisture. If there is more food than the blob can eat in 24 hours, other organisms will move in.
• The Fix:
  1. Use sterile tweezers to carefully remove the moldy oat.
  2. If the mold has spread to the paper towel, you’ll need to “transplant” your blob.
  3. Take a clean piece of the blob that isn’t touching the mold and move it to a fresh, clean container.
• Prevention: Use the “head start” trick. When rehydrating a dormant blob, wait 3-4 hours before adding any food. This gives the blob time to wake up and start its defensive pulses before bacteria can colonize the area.

2. Problem: The Great Escape

You find yellow slime on the outside of your container or all over your desk.

• The Cause: The blob is unhappy. It’s either out of food, or there is too much CO2 (carbon dioxide) inside the container. Airtight lids are the #1 cause of escapes.
• The Fix: Add tiny air holes to your lid. A blob is basically a giant lung; it needs oxygen to breathe.
• The Fix: Make sure the environment isn’t too bright. A blob will “flee” from a desk lamp toward the shadows.

3. Problem: The “Yellow” is Fading

Your blob is turning pale, transparent, or even brownish.

• The Cause: Stress or aging. Like all living things, the plasmodium can get “tired” after weeks of constant growth.
• The Fix: Rejuvenation! This is one of the coolest parts of blob science.
  1. Let your blob dry out naturally onto its paper towel until it becomes a hard crust (

     sclerotium: A hardened, dormant state that allows the slime mold to survive dry conditions for years.

     ).
  2. Wait 48 hours.
  3. Add fresh water and an oat.
  4. The “new” blob that wakes up will be faster, hungrier, and more vibrant than the old one. It’s like a biological reset button.

4. Problem: My Blob Won’t Wake Up

You added water to your dried sclerotium, but 24 hours later, it’s still just a crust.

• The Cause: It might be too cold. or the water you used had too much chlorine.
• The Fix:
  1. Ensure the temperature is between 20°C and 25°C (68°F - 77°F).
  2. Use distilled water or bottled spring water.
  3. Check the age of the sclerotium. While they can live for years, a “fresh” 2-month-old crust wakes up much faster than a 2-year-old one.

Final Tip: If your blob starts making “mushrooms” (tall stalks with black balls on top), it is entering the spore phase. This is the end of its life cycle as a plasmodium. It is trying to have “babies.” You can’t stop this once it starts, but you can collect the spores to start a brand new generation!
