Here is the answer if you are trying to find The Angry Reindeers on day 21 of the 2020 M&S Where’s Wally Advent Calendar.
We’ve had an angry Santa, now its some angry Reindeers, isn’t it all very 2020. Anger. They really don’t look happy though, I wonder what they’re angry about?
You’ll find the angry Reindeer toward the top of the snowy racecourse, the second sleigh down after the ‘milk chocolate calendar’ text box. On the same horizontal line as the Giant Present from day 8.
