Can anyone please tell me any locations of secret shines on the first world..

In Bianco Hills, Secret Shine 1 is from Episode 3 - The Hillside Cave Secret first, you must enter it and reattempt it again. The special stage will now have a red button and when ground pounded, a red coin challenge will begin, giving you 1 minute to get all eight red coins.

Grab the coin on the left as you go up these moving blocks (1). Four coins are now situated at the corners of the orange blocks area; use the hover nozzle to easily make it across to each one (2-5). The remaining three coins are on the three stars either side of the cube area; perform a high jump and hover over to each one (6-8). Once you have them all, the new secret shine will appear at the end of the level.

Secret Shine 2 is from completing Episode 6 - The Secret of the Dirty Lake again, enter the level again. In the special stage, ground pound the red button to start a red coin challenge where you have to collect all eight red coins in 1:30.

Hover over and collect the red coin that is above the red platforms (1) and get the next one above the spinning star (2). Hover over to the cube and to save time, you can jump off earlier and hover to the other side as it moves. Collect the red coin in between the triangles (3) and proceed on to the cube. As it ascends, watch the shadows to determine the locations of the next two coins (4-5). The final three are at the last area of blue and red platforms - two are at opposite corners and the other one is in the middle (6-8). Use the hover nozzle to make this part easier. The shine will be at the end once you get all the coins.

For Bianco Hills and all other levels, there is a 100 yellow coin challenge – you can get a shine by getting 100 coins anywhere – in any level!

Bianca hills right? Once you have beaten stories 3 and 6 go back to them and collect all the red coins within the time limit.
