those are the easiest one to get. you cant miss while you play
but for education, i'll mention them. you can skip or just read.

finish the tutorial 1. play the game.

break your first shell.
obtainable with breaking the houses and vases.

break your second shell.
obtainable with breaking the enemies towers, walls or any unit.

break your rock.
obtainable with jumping on bombs or breaking everything.
or just annoy the iron bull in specific maps.

finish the game.

in case of missing them, you should check these.

use the fireball powerup and hit the door.
dont let your ball wet and dont let your shell break.
its easier to do in tutorial 2 map. shorter and better.

shoot at the enemies rock. if you can't, i'd suggest elephant catapult
and camp at start point or preparing a wall set to stop your enemy and hit it instantly.

kill the flying ship via attack helicopter. it takes a little bit time
but attacking at its bottom will help.

dont break your enemies traps. it requires balance and good riding.
thanks, giant bomb team

save 7000 cash. spamming bank unit will help a lot.
being stingy could help too but doing both will definitely give it to you.

you need to change your rock
in settings and change character section

play with the snowball rock. it doesnt change gameplay
and its good as a skin too.

use the cube rock. it requires balance and good riding.
its stronger and 2 hit can even break the door. practice will help
and your enemy should be slower. jumping will make you faster
and playing a map without any block or hill will make it easier to get
i'd suggest the map l'aquila.

you need a partner to do these. if you dont have,

add me if i could be available, try to find one in community
or add someone who wants to do in the comments.
(please comment if you need one. be friends :D)

play a war game with your friend and win.
its the first step of the troublemaker. it gives trollface boulder.

play skeeboulder and try to get in 6 the most point hole.
you actually dont need a friend for it but i'd suggest for making it healthy.

actually, this one is hardest one to do. if you dont have any friend to gift,
find a fella in community or add me if its urgent. because its impossible in singleplayer.
(if you get the trollface

rules: it must be multiplayer and setted on war game.

easy way to get:
play sparta aka the tutorial 2 map.
be afk in every race and let your friend wins
(dont rush while repeating. it could crash the game.
wait at least 5 seconds before recreating it)
approximately, it takes 40+ minutes to get it (4x10)
it's boring to do but it works.

i'd suggest to place level 3 bank unit in start.
so you can use powerups easily.

harder way to get:
play for fun. theoretically, it takes 1 hour 20 minutes minimum. (8x10)
i'd suggest this one if you play with a friend.

i'd call it, hardest tetralogy
or tetralogical hardness
because these four needs more effort than the others.

i'd suggest the gold time trial if you got other achievements.
you need: a great timing, balance and time control. shortly, practice.
this video will show you the shortcuts with an average speed.
thanks, tsunami643

some keys are hidden behind the rocks
some keys are hold in sky and
some keys are really needs effort.

this playlist would be way useful for get them.
thanks: kab9

you must shoot the barrel bomb unit when the boulder nears to it.
ai is smart. it jumps on it. so you need to spam units to block and camp.

my suggestion is: doing with partner while you do troublemaker achiv.
play war. plant bomb unit. you dont have to use level 2-3 versions.
let your friend to be near to the bomb unit (but he/she must careful to not touch it).
select catapult (level 1 is enough) and shoot the bomb.

for solo: play wallachia. plant the level 1 bomb in near to the rocks.
speedrun the first step and camp on the bait.

this is the only video that i found. sorry about the quality.
if you found or made one, please put on the comments or add me to tell.

dont let your door attacked. its way harder than you think.
i cant give nutshell info. positions are important in here.

this two video would help you:
i used that method. it worked!
thanks, abittal

i tried it a lot, but it was harder for me. you can try this one if it sounds good for you.
