Indeed you do. Holiday Hare '98 was a seperate game, basically a slimmed down JJ2 1.23s, with 5 extra levels, but in all essence it was the shareware.

Later, a CC'99 was made which included the HH'98 episode (which I don't have, nor would I know how it would look in JJ2), so unless you have CC'99 you shouldn't even have that episode in TSF, unless you combined it yourself.
