What's wrong with my deformation retract?

I drew a deformation retract of the twice punctured genus 2-torus. It would seem that this should deformation retract to a bouquet of 3 circles. One the other hand, computing the Euler-characteristics shows that it should deformation retract to a bouquet of 5 circles. If anyone could explain what I'm doing wrong, I would appreciate it!
