Sul sul! Here are some default replacements for ufhairhatllama and umhairhatllama. Both are available for Teens, Young Adults, Adults, and Elders. I changed the flags so they are not marked as hats, enabled for random / townified, and available in all CAS categories. They have been tested on The Sims 2: Ultimate Collection & Legacy Collection.

ufhairhatllama replaced with @platinumaspiration's 4t2 Conversion of Maxis' EP20 Pegacorn. The polycount is the same as the original (5.1k).

umhairhatllama replaced with @miniculesim's 4t2 Conversion of Maxis' EP12 WavyFade. The polycount is the same as the original (3.4k). I used the ombre styles + changed all of the swatches except for the red and grey ones, so that the base hair colour is still represented.
