Here's the request for the third drawn number this year,
. And yeah, it's exactly what it looks like: anthro MLP:FiM tickling.
Specifically Rainbow Dash tickling Fluttershy in stocks - so she won't fly away, probably. Looks like some Discord prank to me.

But yes, 'tickly' (ticklier, tickliest) can refer to something that tickles. Similar to 'ticklish', but ticklish can also mean a person who is sensitive to tickling. 'tickler' on the other hand means 'the person (/thing) that tickles', ie. it is a noun, not an adjective.

Many thanks, bud!
