I dissent I think the tempo fits just fine! In fact, a case could be made that this tempo makes the eventual POP! more effective because it's more of a walking tempo (the GIF about 97 bpm...so Andante) That is just slow enough to kinda lull ya before surprise--just like the famous movement from Haydn's "Surprise" symphony (which incidentally also goes well with this, haha) That tempo is an Andante as well which makes the surprise even better. Do it too fast and the POP loses it's distinctiveness.
So...walk don't run before the POP!
That's my musical case for why that tempo works and I daresay is even better!
