Not slurp but closely allied, I think.
Yesterday/today I had a number of hits from a (new to me) IP range allocated to Yahoo Japan - 18.104.22.168/16.
The IPs hit with a bot-like UA including the word "crawler" on 22.214.171.124/24 - specifically between 126.96.36.199 - 188.8.131.52 but probably most of the /24. There were no proper rDNS entries for the bot IPs.
I have found little information about the bot outside of a few logs reported in SERPS and the URL in the UA is in Japanese - if anyone can translate it I'd be interested.
UA: Y!J-BRW/1.0 crawler (http://help.yahoo.co.jp/help/jp/search/indexing/indexing-15.html)
