After a nymph shows the gobliins which mushroom to take, they get into Vivalzart's House.
Use the Mushroom in the Machine
Have 
Winkle use the mushroom on the machine in the right
side of the screen. Then have 
Fingus press the button on
the machine. The mixture will get stuck at the clothes pin on the shelf.
Get a Piece of Meat
Have Winkle check on the jar above the Piranha to get a
worm. Then have Fingus stand on the square platform beneath
the vulture on the left side of the screen, then have Winkle press the switch beneath the mushroom in a jar, to the left of the machine
on the right side of the room, then quickly switch to Winkle and have him use the worm on the vulture. Fingus will
get a piece of meat and then fall back down.
Get a Bone
Have Fingus use the meat on the piranha in the bottom-right
corner of the room, then pick up the bone that the fish spits out.
Get the Elixir of Kindness
Have Fingus stand on the trash can next to Vivalzart's feet.
Then have Winkle use the bone on Vivalzart.
Fingus will be launched up to the shelf. Have him get the
elixir of kindness, and take the clothespin.
Drink the Mushroom Potion
Then have Fingus use the bottle on the container to the
left of Vivalzart and he will drink the liquid.
Then have Winkle use the bottle on the container.
You will move on to Music Land.
