Zig,
"Fun Bun" - what a ridiculously silly name for a species Philodendron! Your plant is Philodendron goeldii, and it does look something like a Schefflera, especially when it gets large. It can grow almost as large as a P. bipinnatifidum.
Of course, I've already produced several rounds of hybrids featuring this plant as one of the parents. I showed several at IAS. I have one now that is goeldii crossed with one of my dwarf species Philos, and I may show that one at this year's IAS.
Looks like a healthy plant - needs a much larger pot!
