If you've beaten the game, you should know that you lose Tippi. Count Bleck and Tippi disappeared in the Heart Palace and both died. However, don't fear! To get a suitable replacement for Tippi, go to Francis in Chapter 3-4 and buy a new Pixl, Tiptron, from him. Tiptron is basically the same as Tippi, but with a different name.

P.S. Tiptron costs 999 coins!
