I found the three hatty mushrooms, lured the worm into the lake to head back towards the start (though I couldn't scan the starting "tombstone"), scanned the dandelion/maskros and Mt. Sus, scanned the cat and snow clouds.
1. Can the player make it into the hole next to Mt. Sus?
2. I managed to get into the secret tunnel where the bird flies into on the screen below the dandilion (Pujjio?). I ended up falling and couldn't get into the tunnel again, but is there anything to discover right now in there?
3. Can the player make the jump to reach the cat?
4. Anything else that I missed?
