Oh yeah. I forgot all about that one. For a super short event, it had its benefits. 4 SR cards is a minimum of a quick 5k SED. This event was light on the SR Wilds and R gacha that are nice from perocolo, but the Ex Wilds and CRs are great. I walked out with all 5 girls, 7 CRs, 28 Ex Wilds, and a random R wild to finish off my shards. I only had to spend one E-gacha and 3 puddings. I debated not spending the puddings, but at the end, they were enough to bump me up to a slightly higher tier of reward. That got me an extra 30 SR levels (15 to the reward and 15 SR Wilds) and enough shards to get the 7th CR. Seemed like a good trade.
I'm nicely stocked up on Ex Wilds now, so I won't have to burn R-gacha when feeding the rat.
