It took me around 5.5-6 hours to finally score the black-bombshelled version. I think it took around 3 hours for the purple-bombshelled variant.
In addition to what Wain, said: purple bomb / orange body lil crab (1 in 26, or 3.8%) because you need to make sure it doesn't have the explode ability (50/50), it takes quite a long time to get the combination of the color without the selfyeet. Consolation is its very cute
Found this as a backline pet to Underroach. I lucked out and it didn't have the explode ability.
Guessing that the Location map is only for frontline Bombshell Crabs. They seem to be a fairly common backline pet, especially around the Golf Course in SE Undermine.
According to the game database, orange body with purple bomb is the rarest colour (1 in 26, or 3.8%) while red body with black bomb is of medium rarity (5 in 26, or 19.2%). The remainder are purple body with blue bomb (20 in 26, or 76.9%). This pet can also occur as a wild secondary pet, so if you find a secondary with good stats you can always just keep restarting the battle until it appears in the colour you're after.
If you're having trouble capturing this wild pet due to its self-destructing ability, "Explode," I recommend clicking the white flag button to surrender and forfeit the battle. As long as you haven't dealt any damage, it will return to the map, allowing you to start a new battle with a chance of it not having that ability. Usually, after the third surrender, it appears without "Explode," making it much easier to capture for your collection!
