When Trinity wanted to invite Rachael to her 5th birthday party, she figured that all she had to do was drop the invitation in the mail and Rachael would show up. She even told all her friends that Rachael was coming!

Trinity's mom explained to the disappointed girl that Rachael wasn't able to attend because she's so busy -- but Rachael makes it up to Trinity by inviting her to the studio for an early 6th birthday party -- complete with cake, singing, and a gift that brings the biggest smile to the little girl -- a Butterscotch Pony!
