I saw this image of Space Crab:
Then I was like “It’s not included in CI4 or CIU, so why not make a custom attacks for it and interduce it as a new boss?” so here we are. Idk what to call it, it can’t be Space Crab V3.0 since it looks the same as the other ones. It looks like a 2nd version of Crab King, so I guess I call it “Prince Crab”, lol. If you guys got better names feel free to post them in the comments below 
Anyway here’re the attacks of it:
-
Phase 1: It’ll throw Chickens & Chicks like The Iron Chef, left arm, then right arm:
-
Examples:
It’ll do that a couple of times like King Crab so use both arms 3 times, then use the laser arms. It’ll use both laser arms at the same time and move them from pattern 1 to pattern 2 below:
- Pattern 1:
- Pattern 2:
-
-
Phase 2: It’ll use both of it’s laser arms at the same time this round like King Crab at phase 3, so will use both arms 3 times:
-
Examples:
Then use its laser arm again. It’ll be the opposite of laser attack at phase 1 above, it’ll use both arms at the same time from pattern 1 to pattern 2 below:
- Pattern 1:
- Pattern 2:
-
-
Phase 3(FINAL PHASE): This is a new attack, it’ll put its arms on it’s back, shakes them and wait 2 about secs, then throws a bunch of enemies instead of 1 per arm. It’ll do that for 2 times, see the examples below:
-
Examples:
Then use its laser arms at different patterns in-order:
-
Pattern 1:
-
Pattern 2:
-
Pattern 3:
-
Pattern 4:
Please note that:
-
It’s supposed to shot 4 different times and attack in patterns where there’s not supposed to be a safe zone to the player, the player must move from his place in-order to avoid all of the laser patterns. I tried to merge them into 3 patterns but there was still a one safe spot.
-
These patterns may change if this boss gets added because there might be a safe zone still. Arms at pattern 4 supposed to a little higher to cover the corners at top-left & top-right but I couldn’t make the arms reach the corners.
-
-
Yeah, and that’s it, it’ll restart from phase 1 again. If it gets added it should appear from 50% difficulty.
