All Mobs Survive Bikini Bottom Enemy & Creature Guide

Survive Bikini Bottom is not just about surviving nights and upgrading your base. Understanding every mob in the game is just as important. Some mobs help you progress by dropping useful items, while others exist purely to slow you down or end your run. Each mob has different behavior, attack patterns, and drops, so knowing how to deal with them will make surviving past Day 50 or even Day 100 much easier.

Jellyfish – Friendly Resource Mob

Jellyfish are the most common and safest mobs in the game. They do not attack players and are mainly used for farming early-game resources.

How Jellyfish Behave

Jellyfish float around open areas and do not react aggressively. They are often hunted during the day for crafting materials.

How to Farm Jellyfish Safely

1. Approach the jellyfish slowly during daytime.
2. Attack them with basic weapons or tools.
3. Each jellyfish drops 3 Jelly Blobs guaranteed.
4. There is a chance they also drop Chocolate.
5. Collect blobs early to craft tools and upgrades.

Electric Jelly – Hostile Shock Mob

Electric Jelly looks similar to normal jellyfish but is far more dangerous. These mobs deal shock damage over time.

How Electric Jelly Attacks

Electric Jelly shocks players every few seconds once close enough, making it dangerous to stay near them too long.

How to Defeat Electric Jelly

1. Do not stand close for extended periods.
2. Attack quickly and back away between shocks.
3. Use ranged weapons if available.
4. Upon defeat, they drop 3 Jelly Jars guaranteed.
5. They have a chance to drop Jelly Burgers and Kelp Shakes.

Chum Slave (Ranged) – Slow Ranged Enemy

Ranged Chum Slaves are slow but annoying enemies that appear during the day.

How Ranged Chum Slaves Fight

They attack from a distance using crossbows, but their movement speed is very slow.

How to Handle Ranged Chum Slaves

1. Strafe left or right to dodge arrows.
2. Close the distance carefully.
3. Attack during their reload time.
4. They drop 1 Bucket guaranteed.
5. There is a chance they drop Kelp Shakes.

Chum Slave (Melee) – Base Attacker

Melee Chum Slaves are more dangerous than their ranged version because they can raid your base after the early nights.

How Melee Chum Slaves Behave

They often spawn inside buildings and start attacking your base after Night 3.

How to Deal With Melee Chum Slaves

1. Clear nearby houses during daytime.
2. Reinforce your base early.
3. Kite them instead of standing still.
4. Defeat them quickly to avoid base damage.
5. They drop 1 Bucket guaranteed.
6. They have a chance to drop Kelp Shakes.

Clams – Area Damage Mobs

Clams are usually found in groups and attack using area-based damage, making careless fighting very risky.

How Clams Attack

Only one clam attacks at a time, but their AOE damage can hit you if you stand too close.

How to Fight Clams Safely

1. Lure one clam away from the group.
2. Keep a safe distance during attacks.
3. Move in only after the AOE attack ends.
4. Never rush into a herd.
5. Patience is key when farming clams.

Sea Bear – Night-Only Threat

The Sea Bear is one of the most dangerous mobs in the game because it cannot be killed.

How the Sea Bear Works

It only spawns at night and instantly threatens players near the spawn area.

How to Survive the Sea Bear

1. Avoid traveling at night when possible.
2. Hide inside buildings until morning.
3. If it approaches spawn, wait for it to retreat.
4. Do not attempt to fight it—it cannot be harmed.
5. Use night time to prepare instead of exploring.

Knowing how each mob behaves in Survive Bikini Bottom gives you a huge advantage, especially in longer runs. Friendly mobs help you progress, while hostile ones test your timing, movement, and planning. If you learn when to fight, when to dodge, and when to hide, surviving past Day 100 becomes much more realistic. Master the mobs first, and the rest of the game becomes far easier to manage.
