There are two pickups in 'Associations', pickups are small black squares
1. Level 3.4 @0:04
Once you have gotten Laura and Chris up to the second level (Where their end spaces are) the pickup is top right under the small lip, use Laura to bounce Chris up to it. (See video for where I am bouncing)
2. Level 3.8 @0:11
As soon as you begin level John and jump onto the top right square of the 4 moving squares, the pickup is on the top right hand side and you can easily jump to it
Here's a video (Unfortunately I already collected the first one)
