Come Wayward Souls to Potatus et Molassus

People say that they can't find the songs together so here is the best I could do.
Songs are from Over the Garden Wall
Characters are from Over the Garden Wall
Characters:
Wirt
Greg
The Beast
I edited the video, but I don't own the music or drawings, if you know where they came from, please leave a comment.
Lyrics:
Come wayward Souls,
Who wander through the darkness,
There is a light for the lost and the meek.
Sorrow and fear,
Are easily forgotten,
When you submit to the soil of the earth.
Grow, tiny seed,
you are called to the trees.
Rise, 'til your leaves fill the sky,
until your sighs fill the air in the night.
Lift your mighty limbs,
and give praise
to the fire.
O potatus et molassus
Si velis eis quaere a nobis
Lenes et caldi valuti catuli
Plene cum petri dulcibus
O potatus et molassus
Si velis eis quaere a nobis
Lenes et caldi valuti catuli
Potatus et molassus
Grow, tiny seed, you are called to the trees.
