With the "fragile" challenge in Megabonk, you have to complete T1 forest without taking any damage.

Any hits to you is instant GG including fall damage. For this reason, many people take Tony McZoom which a beginner usually do not have unlocked.

Even if you have McZoom unlocked, he is not that great of a pick.

Birdo. Reason why we use Birdo instead of McZoom is that while birdo DOES take fall damage, you can negate this by hitting space for him to float before he hits the ground to negate it.

Also, he literally flies. Keep it in mind the wood spirit CANNOT even hit you in the sky, you have zero chance to get hit unless you fly into the bosses.

Long range stuff - Birdo flies, but sometimes a bit too far above the sky. Keep in mind you do not need all of the items to win - Just 2 out of the 4 would do the trick. In the video, you can see I picked Aegis, there's NO NEED for perfect 4 weapons to win this.

• Sniper rifle
  
• Slutty Rocket
  
• Revolver
  
• Wireless Dagger

You want EXPLOSIVE POWER, not slow builds like EXP. EXP tome is OK if you get it as a first - second pickup, but you are doing one level here.

• Crit tome - Increase the already powerful sniper rifle / rocket
  
• Quantity tome - Needless to say, this allows you to deal with the swarms
  Other tomes are optional.

• Moldy cheese - This is absolutely lethal to bosses at tier 1.
  Unless you legendary items, 1-3 moldy cheeses would have you set for the level.
  
• +1 Jump chances - The more jumps the longer birdo can keep himself in the air.

• Difficulty totems / bonus - You are trying to complete the challenge not make le epic run, less enemy is better
  
• ANY HP buff, ANY regen buff, ANY lifesteal- You don't need them since one hit = death
  
• ANY melee weapons - More distance for birdo the better - For this challenge anyway.

If this helped you complete the challenge, please leave a rating + comment.
This will unlock HOLY BOOK as a purchasable item, which shoots out blast damage when you get heals.
