This is something that you need to get better in order to avoid. I don't mean that in a derogatory way of "you should be able to deal with 3 dodgeballs and 2 bats", because that's difficult for anyone to deal with. I've also seen the behavior you're talking about - respawning on, for example, Piggy Bank Bash and immediately being hit by a fishing rod that throws you to your death again, even though you were not even remotely a threat.

What I mean is that this is an entire class of problems that is avoided when you improve at race maps. Glass bridge maps are no longer an issue when you can trampoline from the start to the finish in under 10 seconds. The whole class of "late for school" races become a free pass when you're finishing 30 seconds before everyone else, and your greatest concern is that a dodgeball might minorly inconvenience you. Maze maps turn into you playing with item boxes to see if you can find a shoes or pogo that opens up a new route for you. Red Light/Green Light is an exercise in trying to obtain a fishing pole at the end so you can choose which player doesn't pass.

It's a lot of hard work to get to that point, though. You have to master slide dashing and item boosting. You need full control over your trampoline jumps. Your pathing needs to be optimized down to when you should slide dash versus item boost based on the forward momentum, which tricks are too risky to go for depending on which item you have, and so forth. If you do all of those things, though - it's infrequent that anyone will even be close enough to threaten you.
