Well, not suprided why yoshi didn't want to enter that place, I mean who wants to go inside?
The animation, though good, still could've used a little more work
The joke was funny
And I like little nuances like the Castle Crasher in the corner
If you were to submit this a second time with a little more work put into the animation, I would rate it at least 4 out of 5
Overall, good job
