Okay, I will provide the English version of the text you provided.
It's time to dance the night away during BitLife's Thunda From Down Unda challenge. Throughout this challenge, you’ll play as an attractive Australian male who’s one of the best dancers around. Things get a little wild here, but that’s what makes this event fun.
BitLife’s Thunda From Down Unda challenge has five objectives to complete:
Be born a male in Australia.
Achieve 100 percent Looks.
Become an exotic dancer.
Hook up with a coworker.
Go to the club.
You only need BitLife’s base game features to complete this challenge. Although having God Mode to change your looks stats can help with the second objective, you’re not required to use it and can easily raise this stat through other means.
The first task of BitLife’s Thunda From Down Unda challenge is to be born a male in Australia. If you don’t have an Australian male available in your Lives list, create a new character whose starting gender is male and whose starting country is Australia.
To make this challenge easier later, try to make a character with high looks stats from the get-go. Ideally, they’ll be born with over 90 percent stats, allowing you to visit the gym a few times to boost them in your childhood and teenage years. Otherwise, if you want to make things harder, you can begin with low stats and progress from there.
There are two parts to achieving 100 percent Looks stats during this challenge. Not only do you need to reach this level, but you need to maintain it until you finish all five objectives. Otherwise, its green checkmark will disappear, returning once you hit 100 percent again.
You can raise your character’s look stats by going to the gym and walking. If you need a quick boost, visit the salon to get waxed, work on your tan, or get your nails done. In extreme cases, you can even get plastic surgery. I’d suggest leaving this task for last, just in case it drops by a few percent by the end.
Once you’re ready to become a dancer, head to your full-time job list and scroll down until you see Exotic Dancer. It’ll appear with a peach emoji beside its name and show up near the bottom of the list. There are no education or work experience requirements, but you will have a much easier time landing this position if you have high looks.
If the job doesn’t appear right away, close and reopen your BitLife app or age up and recheck the list. The job list is completely random, so it may take a few years or resets for it to appear.
After landing a job as an Exotic Dancer, you can head into the Job menu to find your list of coworkers. From here, you’ll have options to befriend, compliment, and talk to your chosen coworker, allowing you to raise your relationship stats.
The key to hooking up with a coworker is to check if they’re single. To do this, select "Ask Out" and, rather than asking them out, check their sexuality and marital status. Although taken NPCs can still say yes to your advances, your odds are higher if they’re single. Once you find someone you’re interested in, head back into their menu and pick "Hook Up" to initiate the advance. Succeed in this once to knock out this task.
The last task of BitLife’s Thunda From Down Unda challenge is to go to a club. This one is simple, as it only requires you to head into Activities, scroll down to Nightlife, and visit any bar. Doing so completes the challenge as long as your looks stats are still 100 percent, rewarding you with a random cosmetic to use on any character you wish.
