As mentioned above, they can change their size (much like the Miniaturekkuri) which they do in order to hunt, intimidate a foe, or to reach alcohol. Alcohol, while not recommended for most yukkuri, is highly recommended for a Suika. In fact, if the Suika doesn't drink at least one cup of alcohol a day it will become ill and depressed. Alcohol is also the only way to heal this yukkuri, as orange juice doesn't appear to work. For that matter, Suikas only drink beer or saké. While they will drink wine as a last resort, presenting wine to a Suika will provoke it to say "what 'da 'ell is 'dis? 'here the booze?". As for food, they respond quite well to watermelons or watermelon-flavored items.
