Any suggestions for 5 year old Super hero party?

[belgianmama]

My ds's 5th birthday is coming up soon. I am having the birthday party at home. The original idea was to hire an entertainer, however due to some financial setbacks lately, we'll have to do without one. My ds wants a superhero party and it'll be fancy dress. I'm struggling a bit with thinking of a few party games for 5 year old boys. Any ideas?

pin the cape on the superman?

instead of musical statues the ordinary way, pose like a super hero.

rescue races (see who can hunt/get to the victim first)

go and buy some of those halloween bargains - spiders webs and such like for about 10p. then you can have treasure hunts in spiderman's web, find the bats for batman etc etc.
Think you're very brave - good luck!!
