With Monkey Tail you seem to have an extra limb. You can catch yourself, climb and do other movement stunts even with both hands full. At the same time your ability to catch dropped objects, you tendency to tightrope walk just for fun and your unusual choice of seating makes you stand out and might even scare ordinary people.
For a character to have an exceptional attribute, outside the "normal" range you must first purchase a specific Pulp Schtick for each sub-attribute. This not only adds a small extra cost, it also gives more or less defined special traits and extraordinary characteristics tied to such high ability scores. Unlike ordinary Pulp schticks, these offer no or very little benefit and some hindrance; they are more flaws than schticks but you still pay for them. If you want to be able to get exceptional attributes but do not want the effects of the schtick, you can pay double price to ignore the effect.
These schticks are considered genre schticks and are not used in all campaigns. See Schticks and Exceptional.
