Ned's Newt
When nine-year-old Ned Flemkin feeds his pet newt a can of Zippo, he ends up turning into a 6-foot shapeshifting pal for life.

When Newton overhears Ned rehearsing his lines as a ring bearer at a family member's wedding, he mistakenly thinks Ned is going to marry someone other than Linda. He takes it upon his own to ruin the wedding, not knowing that it's not Ned who's getting married.
