These were also my last collectibles, and ones I struggled the most with.

1) You just need to be more vigilant as you go down through the cave.

2) There are two ways to solve this, but for both of them you need to realize that your stomp does reach the water level. (from where Toki is standing in the first screenshot)

3) This one involves going through a portal in a bubble.

I finished the second and third levels, but still got stuck in a cave

After the bug fell in an abyss, he aspires to the right, and there electricity, and he will inevitably be lost, and around bats, it is impossible to whistle and it won't help. Where I was mistaken?

Before you can get past the electric slugs, you need to wait for a little while at a certain place in the cave

If I wait, the bug will creep away and he will be killed by slugs. I correctly made everything, it should be sent to that place, near slugs? 3 days I can't make it.

I thought my last hint was already a bit too revealing.
Well, with this one you can't not figure it out: water

At last, AT LAST I guessed! Unambiguously, it is the most unevident puzzle in game. Thanks mtomato!

Could you elaborate on the second screenshot? I have been stuck here for ages. How do I get that birds attention?

You need to distract a frog and when he is aside, send Berrybug up, and then most to climb upward and to stamp when it will be in a corner.
(If to me didn't prompt, never would guess)

oh my god. i never would have thought of it. Like always the solution was much simpler than I thought. Thanks guys!
