Snowglobe

Snowglobe is an Easy ranked parkour course that can be entered by using the command /snowglobe. Upon entering, your inventory is cleared, and replaced with the following items:

Design
Snowglobe is designed to look like a giant snowglobe, with the obstacles the player is jumping on designed to look like snowflakes.

Several snowflakes inside the snowglobe have Music Boxes playing the Underground Hallow theme on them.

Strategy
When jumping from snowflakes with slopes, be careful not to jump off the downward-facing slopes. The game will often detect running down a slope as falling, and cause you to use your boost instead of jumping, which will result in you not clearing the jump.

A snowflake near the end of the course is made of walls and not blocks. Attempting to land on it will result in you falling through it.

Speedrunning
When jumping onto snowflakes made of (painted white) Pink Slime Blocks, use your Cloud in a Bottle right before you fall below it to reduce your downwards velocity and prevent you from bouncing on it. When this is used on both Pink Slime Block snowflakes in the course, it saves approximately 1 second.

Jumping again immediately after jumping onto the Honey snowflake minimizes the time spent walking on the Honey block. Doing this saves about 0.5 seconds.
