For what it is worth, when I got the pineapple whip on Squire's Sweets' opening day, the consistency and flavor were normal. The "whip" was smooth and frozen and had no problem holding up the strawberries that are part of the dessert.
As with all food offerings at BGW, I wouldn't generalize too much from a single experience -- good or bad. The park always seem to be wildly inconsistent in taste, texture, appearance, portion size, and service quality.
