There's a high chance they're not using the loadout you saw in the leaderboard. The Cookie-Pet combination shown in the leaderboard is their "Last Recorded Combi", which is not necessarily the loadout they used to do their high scores.

You may want to check their all-time high by looking at the Try My Friend's Combination section at the bottom of the leaderboard. You'll see their combi used to achieve their all-time high score.
