Halloween 2018 challenge 3 finished. One locked tile left?

Indyana

Hi, I just finished the 3rd challenge of the Halloween 2018 event. I noticed a locked tile in the third level, of which I'll include a screenshot. Diggy is standing right above it.
is this actually a locked tile and if so, how can I unlock it?
I've searched everywhere within the event for a key to no avail, and have checked both this forum, the wiki and the vids posted, to no avail.

I'm sure I'm missing something, but can't figure out what it is. Can someone please help me?

No it does not open.
If you watched the videos you would see they clear it all and do not open that door.
If you have cleared it all then you know it's nothing as well.
Just the devs keeping you on your toes.

As stated above, if you finished the Challenge, then there's nothing to unlock.

When I did this mine last year, I was missing a few tiles & thought they must be behind that door so kept looking for levers as there's no key symbol. Well, in the process of looking for non-existant levers, I found the missing tiles😉

gamemaster thank you. Easter eggs and all, one never knows. So I thought I'ld just ask.
also, not all vids (most don't) show all the quirky extras added, for example when rolling some balls to just a certain location, one gets a bonus.

BlameTheParrot thanks, I did finish the third extra quest, and found all tiles. but kept looking anyway. Might be a hidden hive of cockroaches behind the wall, for all I know.
