While you're playing the different chapter, there is going to be many strawberry that you can get but they require some skills to get it.

To get this achievement, you'll have to collect 30 of them. You can catch as many as possible during playing the story or replay any chapter at any time to get it.

Important : You have to touch the ground after getting a strawberry. if you don't, it won't count.

This achievement is for collecting 30 strawberries...obviously. But how does one collect a strawberry? You have to come in contact with a strawberry and touch the ground for at least one second in a "safe area." Sometimes the immediate area of the strawberry isn't safe or isn't even ground, so you won't be able to collect it.

That being said, there are a set number of strawberries in every level. Chapter One has 20 strawberries in it, leaving you with only 10 more to collect in other chapters. The earliest you can earn this achievement is in Chapter Two, so I'll explain how to get the first 10 strawberries there. Obviously, however, you can collect any 30 strawberries to earn this achievement.

1. From the beginning, head right until you can go through the floor, then go all the way to the bottom. Bust through the right wall and cross the first room into the second. In this room, look at the lower right corner to see another busted wall. Jump and dash your way to stand on top of the floating platform over that busted wall to cause if to fall down. Walk or dash through the wall to find the strawberry.
2. Climb out of the strawberry room and dash up to the wall to climb up to the next room. Walk past the mirror and double back for a cutscene that opens the level up. Dash up through black block and head left to find a long room with several black blocks. Dash through the first one and up through the second one to find the strawberry hidden from plain sight.
3. Dash back out of the black block and cross the rest of the room to come back to the large central area. Dash across and enter the room on the left. For this strawberry, you need to collect all the seeds without touching any ground, be it solid or black block. Touching the ground resets the seeds. The blocks will float around the room in a sort of pattern that eventually leads to them being very close. That is the optimal time to strike, as each seed is as close as possible. Dash up through the two small blocks on the left for a seed, then dash up-right through the large block overhead for the second seed, then finally dash down through the large block below to collect the last seed and make the strawberry form at the bottom of the room. Grab the strawberry and rest.
4. Look in the bottom left corner to see a small piece of the ground that looks different than the rest. Give that a smack and fall through. Behold, the strawberry!
5. Jump back to the center room and make your way to the tippy top to see the strawberry in a very dangerous location. You need to get on top of the black block and dash down to get the strawberry, then dash back up to avoid the spikes and make it back through the block.
6. Fall down to the right and enter the next room. Jump onto the moving platform and dash through the black block ahead to meet the platform on the other side. Jump to the strawberry and climb up to collect it.
7. Fall down and go through the right wall into the next room. Jump and dash through the black block, then dash up-right through the second one to avoid the spikes and grab the strawberry. Climb up and jump and dash through the two black blocks again to collect it back at the start of the room.
8. Cross through the previous room and jump on top of the black block until you are standing over a hole in the ground. Dash downward through the block to find the strawberry sitting around.
9. Go back to the center room and climb all the way up through the ceiling to go back to near the beginning. Look for a giant black block going upward, then dash through it and head right to enter a side room. Jump and dash through both black blocks to find the strawberry, then dash up-left through the first black block to be able to reach the second one to make it back to safety.
10. Return to the large black block and dash down-left through it, then dash up and climb into the ceiling. Dash up-right, then down-right, then up through the first black block. Dash up-right, then left through the second block and climb through the ceiling. After the cutscene, Badeline will start chasing you around with ill intent. Dash through the black block and climb through the ceiling. Dash up-left through the black block, then up-right through it again to reach the strawberry.

On collection of the tenth strawberry in this level, assuming you collected all the strawberries in Chapter One, you'll earn the achievement and have to celebrate after you escape Badeline's clutches.
