My daughter had her 9th birthday party there this year... cost about 125$ for the 4 girls (the rest of her friends were on vacation that week of the 4th of July!) with a package where they could chose any animal in the shop, any outfit for it and also an accessory, they also got to pick 'a sound' to put inside their animals (like a giggle, growl, meow etc). We got a party room & Karaoke machine for 2 hours - we brought the cake & snacks, they provided the plates, napkins & utensils.
The kids had a blast singing & making their animals.... It'll definately be on our list of party ideas for another year.
Party packages are MUCH cheaper than just walking in and making a single one.
