My solution to Oiler went something like this:
1. Bring the 1st vine upwards to guide water to itself through the top hole.
2. Bring the 1st vine towards the base of the 2nd vine to guide water towards it. Make it roughly flat where the water lands on the vine body so water is divided between both vines.
3. Using the yellow shiny, guide the 2nd vine over to the hole above the 1st vine to let water flow into it (this is the step that caused the most headaches, as every time I tried to guide the 2nd vine with the yellow shiny the 1st vine would ride along as well, disrupting the flow of water to the 2nd vine, eventually I managed to use a combination of both the yellow shiny and the blue shiny to let the 2nd vine extend far enough ahead of the 1st vine so only the 2nd vine is within the radius of influence of the yellow shiny).
4. Use blue shiny to shrink 1st vine, then use yellow shiny to guide it towards beehive.
By the way, I don't think having the shinies caught in walls is a framerate issue, it's just that when the cursor moves far enough away from the shiny the cursor loses it, which is nothing wrong, but when you are trying to quickly move the shiny away from vines to stop influencing them and you lose the shiny because you accidentally moved through some walls, it can be quite frustrating.
