Non-Physical Interaction
Non-Physical Interaction is the ability that used to be what the characters had as listed instead of their manipulation of elements such as fire and electricity, for the same justification, being that characters can physically interact with and move characters such as Firey and Lightning, who are made of fire and lightning respectively. The ability listed was changed from Non-Physical Interaction to the manipulation of elements because someone who seemed to not even be familiar with BFDI wrote that the ability seems like that in their opinion, and everyone else found this good. However, I think Non-Physical Interaction is more accurate, and I have reasons.
The ability itself isn't the manipulation of the different states of matter. The characters aren't portrayed as elemental benders in any circumstances; they're portrayed as being able to treat all characters as solid regardless of if those characters have solid bodies or not. In “Elemental Intangibility”, the characters circumvent the “Intangibility”, not control the “Elemental”. The ability to treat non-solid states of matter as solid is Non-Physical Interaction.
