I don't know who needs to hear this, but I just discovered something that has been useful for me. When you get the secret map for the first time and click on it, it only gives you directions (left or right) to find the kangaroo.
However, after finding the kangaroo for the first time, you can use the map to teleport to the kangaroo for free from anywhere or any world, and it has infinite uses. This has made things so much easier for me, and I hope it helps you guys too!
