Blessed bat pun: 蝙蝠→__福 I heard about this pun, but I don't know how to identify the one character.

I've tried a few tricks to search CEDICT but either it doesn't show up or there are too many hits to wade through.
The punch is 五蝠 →五福

A graphic of "five bats" (五蝠) symbolizes 五福臨門 (Five good fortunes come to the household)




Five good fortunes:
「壽(long life)、富(wealth)、貴(status)、安樂(peace)、子孫眾多(many children)。」
