Frozen-Fries Tundra

#Overview

Frozen-Fries Tundra is a climate biome covering the coldest dry parts of the map (the bottom of four temperature bands, dry side). It usually borders Potato Field where it gets warmer and Compost Caves, the cold wet biome.^[1] Its hazard is frost patches that cut Tibo's walking speed to 70% while he is on them. They do no damage.

Frost Fleas open the run, then Snow Molds that split in two (tier 2), fast Field Rats and charging Field Crows (tier 3), the ranged Ice Imp as the only tier 4 pest, and Mud Golems (tier 5). Gold is ×1, but XP is ×1.15, which only Crop Circle beats.

Potato Crates (weight 4) and Spud Shrines (3) are the most common points of interest, with Fry Carts and Microwaves at 2. Beetle Nests, Crop Patches and Moldy Shrines (1) and Boss Lairs (0.4) are rare.

#How it works

#Frost patches

Each chunk centred in the tundra gets 3 or 4 frost patches, each 0.8–1.3 times the base radius of 28; patches that would fall outside the tundra are dropped.^[2] On a patch, Tibo's movement speed is multiplied by 1 − 0.3 = 0.7. The simulation handles chill exactly like the mash in Mash Swamp: it only slows, and overlapping patches do not stack.^[3] Pests are not slowed, and a dash still covers its full distance.^[4]

#Pests and loot

Tiers follow the wave row of two minutes earlier (three on Easy; see Wave schedule). On Normal, Frost Fleas are most spawns until 5:00 and stop at 9:00; Snow Molds lead from 5:00 to 8:00; rats and crows join at 6:00 and lead from 8:00 to 11:00; Ice Imps join at 9:00 and lead until 18:00; Mud Golems join at 16:00 and are the only wave pest from 21:00. When the shooter cap is full (see Crowd limits), a tier 4 roll falls back to a rat or crow.^[5]

Elites from the tundra are Snow Molds until 5:00, rats or crows until 10:00, Ice Imps until 15:00 and Mud Golems after that. The ×1.15 XP applies to pests that die inside the tundra.^[6][7] Standard's late-run XP step multiplies pest XP before this biome bonus.

#Tips

• On frost Tibo walks at about 43 units per second at base speed. That is slower than Field Rats (50) and only a little faster than Field Crows (40) between charges, so frost patches are bad places to be caught by tier 3 pests.
• The frost is mild compared with Mash Swamp, and the tundra's XP bonus makes it a good place to level, especially from about 9:00 to 18:00 when Ice Imps (7 XP each) make up a large share of spawns.
• Ice Imps fire a three-shot fan. Keep moving sideways to them rather than backing away in a straight line.

#Enemies

Each biome lists its pests in five tiers.

Tier	Enemies
1	Frost Flea
2	Snow Mold
3	Field Rat, Field Crow
4	Ice Imp
5	Mud Golem

#Points of interest

Relative spawn weights for points of interest in this biome (poiWeights). Each chunk tries to place up to 2 (poisPerChunk) with 35% chance, otherwise 1; crowded spots and the overtime taper can mean fewer.

#Props

ice-fry, snow-drift, frozen-crate (10 per chunk).
