Question for those who read the junior novelization-spoilers

The last we see of Ken and Barbie is when Lotso throws them in the dumpster. Then at the end, Andy gives his toys to Bonnie, but Barbie and Ken are nowhere to be seen. Where did they go?

My deepest apologizes for the spoilers, but I really do what to know -Omar

[spoil]They’re still at Sunnyside. Barbie wanted to go with Woody and the toys but Ken kept her back. But the thing I like about the ending is that the toys can still visit the non-corrupt Sunnyside through Bonnie.[/spoil]

Thanks so much Bryko614! It was unclear when I read it online. -Omar
