Didi has replaced Goober by Reptar but Tommy really disagree and keep his Reptar.

Didi, worry, call Doctor Lipchitz. Someone advice her to take her children into a park where Goober is.

When Tommy met Goober, this one stole his Reptar and give him a Goober ! Few seconds later during one second, we can see that Tommy's Reptar is back in the push chair !
